Caffeine works by blocking adenosine receptors in the brain. Adenosine is a chemical that builds up during waking hours and makes you feel drowsy; by blocking its receptors, caffeine prevents that drowsy signal from reaching the brain, keeping you alert. Which sentence best summarizes the passage?
Answer: Caffeine maintains alertness by blocking the brain receptors that normally receive the chemical responsible for making you feel sleepy.
Option A concisely restates the mechanism: caffeine blocks receptors for the sleepiness-causing chemical adenosine, thus keeping the brain alert.
Iceland generates almost 100% of its electricity from renewable sources, primarily geothermal and hydropower. Its unique geological position on the Mid-Atlantic Ridge provides abundant volcanic heat, making geothermal energy unusually practical there. Which is the best paraphrase of the second sentence?
Answer: Because Iceland sits on the Mid-Atlantic Ridge, it has access to exceptional volcanic heat that makes geothermal energy especially feasible.
Option A correctly rephrases the geological location, the resulting volcanic heat, and why geothermal energy is particularly practical in Iceland.
Dogs were domesticated from wolves at least 15,000 years ago, making them the first domesticated animal. Through selective breeding over millennia, humans developed hundreds of breeds with distinct physical traits and behavioral tendencies suited to specific tasks. Which is the most concise and accurate restatement?
Answer: Dogs, domesticated from wolves over 15,000 years ago, were shaped through centuries of selective breeding into hundreds of specialized breeds.
Option A captures the 15,000-year timeline, the wolf origin, and the breeding process that created specialized breeds — all key points in two sentences.
The ozone layer absorbs the majority of the Sun's ultraviolet radiation before it reaches Earth's surface. Without this protective shield, increased UV exposure would cause higher rates of skin cancer and cataracts in humans and damage plant and marine ecosystems. Which sentence best paraphrases the second sentence?
Answer: If the ozone layer were absent, greater UV radiation would lead to more skin cancer and eye disease in people and devastate plant and ocean ecosystems.
Option A accurately paraphrases the hypothetical scenario and all three categories of harm — human health (skin/eyes) and ecological damage — mentioned in the sentence.
The Wright Brothers' first powered flight in 1903 lasted only 12 seconds and covered 120 feet. Yet within two decades, commercial aviation had begun, and by mid-century, jet engines had made intercontinental travel routine for millions of people. Which is the best summary?
Answer: The Wright Brothers' brief inaugural flight in 1903 launched an aviation revolution that within fifty years made long-distance air travel common.
Option A captures the modest start in 1903, the rapid progression, and the eventual commonplace status of intercontinental air travel — the arc of the entire passage.
Plastic pollution poses a serious threat to marine life. Sea turtles often mistake plastic bags for jellyfish, ingesting them and blocking their digestive systems. Microplastics have also been found in the tissues of fish, crustaceans, and even deep-sea organisms. Which option most accurately paraphrases the passage?
Answer: Marine animals are endangered by plastic waste, which they sometimes eat by mistake and which has penetrated even the deepest ocean organisms.
Option A correctly generalizes both the specific turtle example and the microplastic finding to convey the broad marine threat without overstating any specific claim.
Languages evolve continuously. New words enter the lexicon through technology, culture, and contact with other languages, while archaic words fade from use. Linguists estimate that English adds thousands of new words each decade. What is the best summary of this passage?
Answer: Language is a living system that constantly changes as new words are added and old ones disappear, with English gaining thousands of new words every ten years.
Option A summarizes the cyclical nature of language change (addition and loss), the causes, and the quantitative example from the passage.
