Correct! Wrong!

6) In the town of RodPowersville, all the license plates have four characters. The first character is always an R or a P. The second and third characters are digits between 0 and 9. The fourth character is a single letter of the alphabet from A to Z. How many possible license plates are there?

Correct! Wrong!

There are two possibilities (R and P) for the first character. There are ten possible choices (0 through 9) for the second and third characters. There are 26 letters in the alphabet, so there are 26 possible choices for the last characters. Applying the multiplication principle, you get 2 × 10 × 10 × 26 = 5,200.

7) John wants to buy a new computer that costs $3,280. He decides to use his own car and hire out as a taxi during the four months of summer. It costs him $693 to insure his car for those four months. He spends $452 per month on gas. Assuming no other expenses, how many fares will he have to get before he earns enough money for the computer, if he charges an average of $7 per fare?

Correct! Wrong!

John needs to make the cost of his expenses, plus the cost of the new computer: $3,280 + $693 + ($452 × 4) = $3,280 + $693 + $1,808 = $5,781. Each fare averages $7, so, to find the number of fares: 5781/7 = 825.85. Because a fraction of a fare isn’t practical, round this up to 826 fares.

8) Jeanie has twice as many quarters as nickels. She has a total of $8.25. How many quarters does she have?

Correct! Wrong!

Let x = the number of nickels. That means 2x = the number of quarters. All of Jeanie’s coins total $8.25 or 825 cents. Mathematically, this can be expressed as: 5(x)+25(2x)=825, 5x+50x=825, 55x= 825, x=825/55, x=15. Jeanie has 15 nickels.

9) Patty is 45 years old. She is 15 years older than twice her daughter’s age. How old is Patty’s daughter?

Correct! Wrong!

You want to find out Patty’s daughter’s age, so let d = daughter’s age. You know that Patty is 45 and her age is 15 years more than twice the daughter’s age. This can be expressed mathematically as 45 = 2d + 15. The rest is simply skull-sweat. 45-15=2d, 30=2d, 30/2 = d, d=15

10) Patrick was going to buy a car for $5,800. The car dealer offered him two options for buying the car: He could pay the full amount in cash, plus 10 percent for tax and license, or he could pay $1,000 down and $230 a month for 24 months, and the dealer would pick up the tax and license costs. Which is the better deal?

Correct! Wrong!

First, compute the total cost of the cash plan: $5,800 + 10 percent = $5,800 + $580 =$6,380. The total cost of the payment plan would be $1,000 + ($230 × 24) = $6,520. The cash plan is a better deal.

11) Cognizant most nearly means

Cognizant is an adjective meaning aware.

12) Abbreviate most nearly means

15) Ardent most nearly means

Correct! Wrong!

Ardent is an adjective that means characterized by warmth of feeling, typically expressed in eager, zealous support or activity.

16) Which of the following would be the best title for this passage?

Correct! Wrong!

A question that asks you to choose a title for the passage is the main idea question. This main idea is expressed in the second sentence, the topic sentence: It is important for firefighters to be able to recognize each of these types of burns so that they can be sure burn victims are given proper treatment. Choice b expresses this idea and is the only title that encompasses all of the ideas expressed in the passage. Choice a is too limited; it deals only with one of the kinds of burns discussed in the passage. Likewise, choices c and d are also too limited. Choice c covers types of burns but not their treatment, and d deals only with preventing infection, which is only a secondary part of the discussion of treatment.

17) Second-degree burns should be treated with

Correct! Wrong!

The answer to this fact question is clearly expressed in the sentence, “These burns should be immersed in warm water and then wrapped in a sterile dressing or bandage.” The hard part is keeping track of whether “These burns” refers to the kind of burns in the question, which is second-degree burns. It’s easy to choose the wrong answer here because all of the answer choices are mentioned in the passage. You need to read carefully to be sure you match the right burn to the right treatment.

18) First-degree burns turn the skin

Correct! Wrong!

This is another fact or detail question. The passage says that a first-degree burn “causes the skin to turn red.” Again, it’s important to read carefully because all of the answer choices (except b, which can be eliminated immediately) are listed elsewhere in the passage.

19) Which of the following best expresses the main idea of the passage?

Correct! Wrong!

Clearly this is the main idea question, and c is the only answer that encompasses the whole passage. Choices b and d are limited to particular burns or treatments, and answer a discusses only burns and not their treatment. In addition, the second sentence tells us that “It is important for firefighters to be able to recognize each of these types of burns so that they can be sure burn victims are given proper medical treatment.”

20) The word “irate” as it is used in the passage most nearly means

Correct! Wrong!

This is a vocabulary question. Irate means ill-tempered, angry. It should be clear that b, happy, cheerful, is not the answer; dealing with happy patients is normally not a great challenge. Patients that are irregular, odd, or d, sloppy, lazy, may be a challenge in their own way, but they aren’t likely to rouse a healthcare worker to anger. In addition, the passage explains that irate patients are not “angry at you,” and irate is used as a synonym for irritable, which describes the patients under discussion in the very first sentence.

21) The passage suggests that healthcare workers

Correct! Wrong!

This is an inference question, as the phrase “The passage suggests” might have told you. The idea that angry healthcare workers might give inadequate treatment is implied by the passage as a whole, which seems to be an attempt to prevent angry reactions to irate patients. Furthermore, the last sentence, in particular, makes this inference possible: If you react to this behavior with anger . . . you both lose because the patient is less likely to get the proper care. Choice c is not correct, because while it maybe true that some irate patients have sued the hospital in the past, there is no mention of suits anywhere in this passage. Likewise, choice b is incorrect; the passage does suggest ignoring patients’ insults, but nowhere does it recommend not talking to patients—it simply recommends not talking angrily. And while it may be true that some healthcare workers may lose control of their emotions, the passage does not provide any facts or details to support answer a, that they “easily lose control.” Watch out for keywords like easily that may distort the intent of the passage.

22) An “imprecation” is most likely

Correct! Wrong!

If you didn’t know what an imprecation is, the context should reveal that it’s something you can ignore, so neither choice a, an object, nor choice d, a medication, is a likely answer. Furthermore, choice c is not likely either, since an irate patient is not likely to be making jokes.

23) Which of the following best expresses the writer’s views about irate patients?

Correct! Wrong!

The writer seems to believe that some irate patients just want attention, as is suggested by, “Often these patients will purposely try to anger you just to get some reaction out of you. If you react to this behavior with anger, they win by getting your attention.” It should be clear that choice b cannot be the answer because it includes an absolute: “Irate patients are always miserable.” Perhaps some of the patients are often miserable, but an absolute like always is almost always wrong. Besides, this passage refers to patients who maybe irate in the hospital, but we have no indication of what these patients are like at other times, and miserable and irate are not exactly the same thing, either. Choice c is also incorrect because the purpose of the passage is to ensure that patients receive proper treatment and that irate patients are not discriminated against because of their behavior. Thus, irate patients should be made to wait for treatment is not a logical answer. Finally, d cannot be correct because though it may be true, there is no discussion of career advancement in the passage.

24) What’s the equation of a line that passes through points (0, -1) and (2, 3)?

Correct! Wrong!

38) An engine is using too much oil. Which one of the following is the most likely cause?

Correct! Wrong!
