Math Reading Questions Test 2
According to the experiment described in Passage 2, whether the authorโs ravens continued to show interest in a formerly new object was dictated primarily by whether that object was
Choice A is the best answer. The last paragraph of Passage 2 presents the results of an experiment in which the author scattered unfamiliar objects in the path of some ravens. According to the passage, the birds initially โcontacted all new objects preferentiallyโ but in โsubsequent trialsโ only preferred those โpreviously novel itemsโ that โwere edibleโ (Passage 2, lines 19-25). Choice B is not the best answer because the ravens studied by the author only preferred those โpreviously novel itemsโ that โwere edible,โ whereas โthe inedible objects became โbackgroundโ items, just like the leaves, grass, and pebblesโ (Passage 2, lines 19-25). In other words, plentiful items did not continue to interest the ravens unless the items were edible. Choice C is not the best answer because the ravens studied by the author only preferred those โpreviously novel itemsโ that โwere edible,โ whereas โthe inedible objects became โbackgroundโ items, just like the leaves, grass, and pebbles, even if they were highly conspicuousโ (Passage 2, lines 19-25). In other words, conspicuous items did not continue to interest the ravens unless the items were edible. Choice D is not the best answer because the ravens studied by the author only preferred those โpreviously novel itemsโ that โwere edible,โ whereas โthe inedible objects became โbackgroundโ items, just like the leaves, grass, and pebblesโ (Passage 2, lines 19-25). In other words, natural items did not continue to interest the ravens unless the items were edible.
Within Passage 1, the main purpose of the first two paragraphs (lines 1โ7) is to
Choice B is the best answer. Passage 1 opens with an explanation of Morganโs canon and continues with a discussion of peopleโs expectations regarding animal intelligence. Taken together, the first two paragraphs indicate that despite cautions to the contrary, people still tend to look for humanlike levels of intelligence in many animals, including birds. These two paragraphs provide a framework in which to assess the work of Gray and Hunt, presented in the rest of the passage. The passageโs characterization of the experiment Gray and Hunt conduct, in which they observe a crowโs tool-making ability and to which Gray responds by trying and failing to mimic the birdโs behavior (โI had a go, and I couldnโt do it,โ Passage 1, line 25), suggests that Shettleworth, quoted in the second paragraph, is at least partially correct in her assessment that โWe somehow want to prove [birds] are as โsmartโ as peopleโ (Passage 1, lines 5โ5). Choice A is not the best answer because while the reference to Morganโs canon in the first paragraph offers a sort of historical background (given that the canon was published in 1894), the second paragraph describes peopleโs continuing expectations regarding animal intelligence. Furthermore, the fact that Gray and Hunt may share with other people the tendency to look for humanlike intelligence in many animals does not by itself establish that the main purpose of the first two paragraphs is to question the uniqueness of Gray and Huntโs findings. Choice C is not the best answer because while the reference to Morganโs canon in the first paragraph does introduce a scientific principle, the discussion in the second paragraph of peopleโs expectations regarding animal intelligence, as well as the passageโs characterization of Gray and Huntโs experiment and how the researchers interpret the results, primarily suggest that people tend to violate the canon by attributing humanlike levels of intelligence to many animals. Choice D is not the best answer because although the first two paragraphs do present different perspectives, they are not seemingly or genuinely contradictory. The second paragraph, particularly the quotation from Shettleworth, serves mainly to qualify (not contradict) the position staked out in the first paragraph by suggesting that while Morganโs canon is probably a sound principle, people still tend to project humanlike levels of intelligence onto many animals. Moreover, the experiment depicted in the rest of the passage primarily bears out Shettleworthโs claim that โWe somehow want to prove [birds] are as โsmartโ as peopleโ (Passage 1, lines 5โ5) and thus does not reconcile the perspectives found in the opening paragraphs.
Which choice provides the best evidence for the answer to the previous question?
Choice C is the best answer because in lines 38โ40, Jordan draws a contrast between political motivations and โhigh crime[s] and misdemeanorsโ as the basis for impeachment and argues that impeachment โmust proceed within the confinesโ of the latter concept. These lines thus serve as the best evidence for the answer to the previous question. Choice A is not the best answer because lines 10โ12 only address a misconception that Jordan contends some people have about what a vote for impeachment means. These lines thus do not serve as the best evidence for the answer to the previous question. Choice B is not the best answer because lines 15โ18 only speak to a division of responsibility between the two houses of the U.S. Congress. These lines thus do not serve as the best evidence for the answer to the previous question. Choice D is not the best answer because lines 45โ47 (โCongress...transportationโ) serve mainly to indicate that the U.S. Congress has an extensive and important agenda. These lines thus do not serve as the best evidence for the answer to the previous question.
One difference between the experiments described in the two passages is that unlike the researchers discussed in Passage 1, the author of Passage 2
Choice B is the best answer. The researchers described in Passage 1 โhid behind a blindโ (Passage 1, line 16) to avoid being seen by the crow. The author of Passage 2, on the other hand, made no attempt to conceal his presence; in fact, as he describes it, he โledโ the ravens in his study on โwalksโ (Passage 2, lines 1โ2), during which he โtouched specific objectsโ (Passage 2, line 4) and then watched to see whether the birds touched the same objects. The author of Passage 2 notes that the ravens โsoon became more independentโ (Passage 2, line 8), going their own way rather than continuing to follow the author. From this it is clear that the author of Passage 2, unlike the researchers described in Passage 1, intentionally made the birds aware of his presence. Choice A is not the best answer because while a case could be made that the author of Passage 2 gave the ravens a problem to solve (Which new objects are best to touch?), the researchers described in Passage 1 presented the crows with a problem as well: how to extract meat from a log. Thus, presenting birds with a problem to solve was not a difference between the experiments. Choice C is not the best answer because both the researchers described in Passage 1 and the author of Passage 2 consciously manipulated the birdsโ surroundings. The crow researchers placed meat pieces in a log and a pandanus plant behind the log (see Passage 1, lines 15โ16). The author of Passage 2 put unfamiliar objects on a path for the ravens to find (see Passage 2, lines 13โ14). Thus, conscious manipulation of the birdsโ surroundings was not a difference between the experiments. Choice D is not the best answer because there is no evidence that the author of Passage 2 tested the ravensโ tool-using abilities. The passage instead indicates that the author recorded observations about the birdsโ interactions with objects naturally occurring in and artificially introduced into the environment.
Is the main conclusion presented by the author of Passage 2 consistent with Morganโs canon, as described in Passage 1?
Choice D is the best answer. According to Passage 1, Morganโs canon is โthe principle that suggestions of humanlike mental processes behind an animalโs behavior should be rejected if a simpler explanation will doโ (Passage 1, lines 1โ3). The main conclusion drawn by the author of Passage 2 is that โravensโ curiosity ensures exposure to all or almost all items in the environmentโ (Passage 2, lines 25โ26). In referring to the ravensโ behavior as reflecting โcuriosity,โ a human trait, the author of Passage 2 would seem to be ascribing a humanlike mental process to an animalโs behavior without explicitly considering alternate explanations. Choice A is not the best answer because the main conclusion drawn by the author of Passage 2 is that โravensโ curiosity ensures exposure to all or almost all items in the environmentโ (Passage 2, lines 25โ26). In referring to the ravensโ behavior as reflecting โcuriosity,โ a human trait, the author of Passage 2 would seem to be ascribing a humanlike mental process to an animalโs behavior without explicitly considering alternate explanations. Morganโs canon holds that such suggestions should be rejected unless a โsimpler explanationโ cannot be found (Passage 1, lines 1โ3); therefore, the conclusion the author of Passage 2 reaches is not consistent with Morganโs canon. Moreover, by ascribing the ravensโ behavior to โcuriosity,โ the author of Passage 2 seems to reject environmental factors as the cause. Choice B is not the best answer because the main conclusion drawn by the author of Passage 2 is that โravensโ curiosity ensures exposure to all or almost all items in the environmentโ (Passage 2, lines 25โ26). In referring to the ravensโ behavior as reflecting โcuriosity,โ a human trait, the author of Passage 2 would seem to be ascribing a humanlike mental process to an animalโs behavior without explicitly considering alternate explanations. Morganโs canon holds that such suggestions should be rejected unless a โsimpler explanationโ cannot be found (Passage 1, lines 1โ3); therefore, the conclusion the author of Passage 2 reaches cannot be the type of โsimpler explanationโ Morgan was alluding to. Choice C is not the best answer because while the main conclusion drawn by the author of Passage 2 is not consistent with Morganโs canon (see explanation for choice D), nothing about how the canon is described in Passage 1 precludes the possibility that animals can exhibit complex behavior patterns. The canon merely rejects the idea that humanlike mental processes should quickly or easily be attributed to animals.
The stance Jordan takes in the passage is best described as that of
Choice A is the best answer. Jordan helps establish her idealism by declaring that she is an โinquisitorโ (line 1) and that her โfaith in the Constitution is whole; it is complete; it is totalโ (line 2). At numerous points in the passage, Jordan sets forth principles (e.g., โThe powers relating to impeachment are an essential check in the hands of the body of the legislature against and upon the encroachments of the executive,โ in lines 13โ15) and makes reference to important documents that do the same, including the U.S. Constitution and Federalist No. 65. Choice B is not the best answer because although Jordan is advocating a position, there is no evidence in the passage that she is seeking a compromise position. Indeed, she notes that she is โnot going to sit here and be an idle spectator to the diminution, the subversion, the destruction, of the Constitutionโ (lines 3โ4), indicating that she is not seeking compromise. Choice C is not the best answer because Jordan is a participant (โan inquisitor,โ line 1) in the proceedings, not a mere observer. Indeed, she notes that she is โnot going to sit here and be an idle spectator to the diminution, the subversion, the destruction, of the Constitutionโ (lines 3โ4). Choice D is not the best answer because Jordan is identified as a congresswoman and (โan inquisitor,โ line 1), not a scholar, and because she is primarily discussing events happening at the moment, not researching an unidentified historical controversy. While she refers to historical documents and individuals, her main emphasis is on the (then) present impeachment hearings.
The crows in Passage 1 and the ravens in Passage 2 shared which trait?
Choice A is the best answer. Both bird species studied modified their behavior in response to changes in their environment. The researchers described in Passage 1 โhad gotten wild crows used to finding meat tidbits in holes in a logโ (Passage 1, lines 14โ15). In other words, the researchers had repeatedly placed meat in the logโthat is, changed the crowsโ environmentโand the birds had responded by modifying their behavior, a point reinforced in Passage 1, line 15, which note that the birds began โchecking the log reliably.โ The ravens in Passage 2 act in analogous fashion, responding to the introduction of new objects in their environment by โpick[ing] them out at a rate of up to tens of thousands of times greater than background or previously contacted objectsโ (Passage 2, lines 20โ21). Choice B is not the best answer because while there is some evidence that the ravens described in Passage 2 formed a bond with the author, going on walks with him and possibly viewing him as their โteacher,โ there is no evidence that a similar bond formed between the researchers described in Passage 1 and the crows they studied. Indeed, these researchers โhid behind a blindโ (Passage 1, line 16) in an effort to avoid contact with their subjects. Choice C is not the best answer because while crowsโ tool manufacture is the central focus of the experiment described in Passage 1, there is no evidence that the ravens in Passage 2 did anything similar. Passage 1 does mention that โsome ravensโ use โseemingly insightful string-pulling solutionsโ (Passage 1, line 30), but nothing in Passage 2 suggests that the ravens in that particular study had or displayed tool-making abilities. Choice D is not the best answer because while there is some evidence that the ravens described in Passage 2 mimicked human behavior, going on walks with the author and possibly viewing him as their โteacher,โ there is no evidence that the crows in Passage 1 did any mimicking. Passage 1, in fact, suggests that the ability of the crow to produce the meat-fishing tool was innate rather than a skill it had acquired from either humans or other birds.
It can reasonably be inferred from the passage and graphic that if scientists adjusted the coils to reverse the magnetic field simulating that in the East Atlantic (Cape Verde Islands), the hatchlings would most likely swim in which direction?
Choice B is the best answer. The passage notes that Lohmann, who studied loggerhead turtle hatchlings โin a large water tank surrounded by a large grid of electromagnetic coilsโ (lines 11โ12) capable of manipulating the magnetic field around the turtles, discovered that the hatchlings would start โswimming in the opposite directionโ when he โreverse12 the direction of the magnetic field around themโ (lines 12โ14). The graphic (whose caption establishes that geographic north is represented by 0 degrees) indicates that loggerhead hatchlings tested in a magnetic field that simulates a position at the east side of the Atlantic near the Cape Verde Islands would normally travel in a southwesterly direction (around 218 degrees). Given the above information, it is reasonable to infer that if the magnetic field were reversed, the turtles would travel in a northeasterly direction. Choice A is not the best answer because information in the passage and graphic suggests that the loggerhead turtle hatchlings would travel in a northeasterly, and not a northwesterly, direction if scientists reversed the magnetic field simulating a position at the east side of the Atlantic near the Cape Verde Islands. Choice C is not the best answer because information in the passage and graphic suggests that the loggerhead turtle hatchlings would travel in a northeasterly, and not a southeasterly, direction if scientists reversed the magnetic field simulating a position at the east side of the Atlantic near the Cape Verde Islands. Choice D is not the best answer because information in the passage and graphic suggests that the loggerhead turtle hatchlings would travel in a northeasterly, and not a southwesterly, direction if scientists reversed the magnetic field simulating a position at the east side of the Atlantic near the Cape Verde Islands. The graphic indicates that the hatchlings travel southwesterly under the normal (nonreversed) simulated conditions.
In lines 34โ37 (โProsecutions...senseโ), what is the most likely reason Jordan draws a distinction between two types of โpartiesโ?
Choice A is the best answer. Jordan is making a distinction between two types of โpartiesโ: the informal associations to which Alexander Hamilton refers and formal, organized political parties such as the modern-day Republican and Democratic parties. Jordan anticipates that listeners to her speech might misinterpret her use of Hamiltonโs quotation as suggesting that she thinks impeachment is essentially a tool of organized political parties to achieve partisan ends, with one party attacking and another defending the president. Throughout the passage and notably in the seventh paragraph (lines 38โ43), Jordan makes clear that she thinks impeachment should be reserved only for the most serious of offenses โ ones that should rankle people of any political affiliation. Choice B is not the best answer because Jordan offers no objection to Hamiltonโs notion that impeachment proceedings excite passions. Indeed, she quotes Hamilton extensively in a way that indicates that she fundamentally agrees with his view on impeachment. Moreover, she acknowledges that her own speech is impassioned โ that she feels a โsolemnnessโ (line 2) and a willingness to indulge in โhyperboleโ (line 1). Choice C is not the best answer because Jordan offers no objection to Hamiltonโs level of support for the concept of impeachment. Indeed, she quotes Hamilton extensively in a way that indicates that she fundamentally agrees with his view on impeachment. Choice D is not the best answer because Jordan suggests that she and her fellow members of Congress are โtrying to be bigโ (line 48), or high- minded, rather than decide the present case on the basis of politics. Indeed, throughout the last four paragraphs of the passage (lines 26โ49), she elaborates on the principled, just basis on which impeachment should proceed. Moreover, throughout the passage Jordan is focused on the present impeachment hearings, not on the justice or injustice of impeachments generally.
The author refers to reed warblers and sparrows (line 33) primarily to
Choice B is the best answer because the author indicates that reed warblers and sparrows, like loggerhead turtles, had previously been known to have โsome way of working out longitudeโ (line 34). Choice A is not the best answer because although the author notes that loggerhead turtles, reed warblers, and sparrows are all โanimal migrantsโ (line 33), he offers no specifics about reed warblersโ and sparrowsโ migration patterns, and the only connection he draws among the three animals is their recognized ability of somehow โworking out longitudeโ (line 34). Choice C is not the best answer because the author only mentions three โanimal migrantsโ by name (loggerhead turtles, reed warblers, and sparrows) and indicates that โseveralโ such migrants had previously been known to have โsome way of working out longitudeโ (line 34). He makes no claim in the passage that most animal species have some long-distance navigation ability. Choice D is not the best answer because although the author indicates that reed warblers and sparrows, like loggerhead turtles, are โanimal migrantsโ (line 33), he offers no specifics about how the ability to navigate long distances might help reed warblers and sparrows (nor, for that matter, much information about how this ability might help loggerhead turtles).
The main rhetorical effect of the series of three phrases beginning in line 4 (โthe diminution, the subversion, the destructionโ) is to
Choice A is the best answer because the quoted phrases โ building from โdiminutionโ to โsubversionโ to โdestructionโ โ suggest the increasing seriousness of the threat Jordan sees to the Constitution. Choice B is not the best answer because the passage offers no evidence that the quoted phrases refer to three different events that happened in a strict sequence. It is more reasonable to infer from the passage that Jordan sees โdiminution,โ โsubversion,โ and โdestructionโ as differing degrees to which the Constitution could be undermined. Moreover, the passage suggests that Jordan sees these three things as products of the same action or series of actions, not as three distinct stages in a process. Choice C is not the best answer because the passage offers no evidence that the quoted phrases refer to three distinct ways in which the Constitution is prone to failure. It is more reasonable to infer from the passage that Jordan sees โdiminution,โ โsubversion,โ and โdestructionโ as differing degrees to which the Constitution could be undermined. Moreover, the passage suggests that Jordan sees these three things as products of the same action or series of actions, not as three distinct โways.โ Choice D is not the best answer because the passage offers no evidence that the quoted phrases refer to three unique elements of a proposal to resolve a crisis. It is more reasonable to infer from the passage that Jordan sees โdiminution,โ โsubversion,โ and โdestructionโ as differing degrees to which the Constitution could be undermined. Moreover, the passage suggests that Jordan sees these three things as products of the same action or series of actions, not as three distinct โparts.โ
As used in line 26, โchanneledโ most nearly means
Choice C is the best answer because the context makes clear that the kind of โexceptionโ (line 26) Jordan describes should be narrowly constrained, or limited. As lines 27โ29 indicate, the Federal Convention of 1787 โlimited impeachment to high crimes and misdemeanors, and discounted and opposed the term โmaladministration,โโ presumably because the term implied too broad a scope for the exception. Choice A is not the best answer because while โchanneledโ sometimes means โworn,โ it would make no sense in context to say that the kind of โexceptionโ (line 26) Jordan describes should be narrowly worn. Choice B is not the best answer because while โchanneledโ sometimes means โsent,โ it would make no sense in context to say that the kind of โexceptionโ (line 26) Jordan describes should be narrowly sent. Choice D is not the best answer because while โchanneledโ sometimes means โsiphoned,โ it would make no sense in context to say that the kind of โexceptionโ (line 26) Jordan describes should be narrowly siphoned.
