Read the following passage, then answer the question below. For most of the twentieth century, neurologists held that the adult brain was fixed: once the developmental window closed, its wiring was set for life. Evidence gathered since the 1990s has overturned that view. Studies of stroke patients showed that undamaged regions could gradually assume functions once handled by destroyed tissue, and imaging of trained musicians revealed measurably enlarged motor areas corresponding to the fingers they used most. Researchers now describe the mature brain as plastic, capable of reorganizing its connections in response to injury, practice, and environment. The shift in terminology mattered: it moved rehabilitation away from managing permanent loss and toward actively retraining the nervous system. As used in the passage, the word 'plastic' most nearly means:
Correct answer: A - capable of being reshaped
Read the following passage, then answer the question below. When Bogota opened its rapid bus network in 2000, planners expected the main benefit to be shorter commutes. Travel times did fall, by an average of eighteen minutes for riders on the busiest corridors. But the effect that surprised the planning team appeared in the municipal health records. Along the new routes, reported respiratory illness among children under ten declined by roughly a fifth over the following four years, a change researchers attributed to the removal of thousands of aging diesel minibuses from those streets. Property values near the stations also rose, though analysts still disagree about how much of that increase reflected the transit line itself rather than a broader economic expansion underway at the time. According to the passage, the outcome that planners did not anticipate was:
Correct answer: C - the decline in respiratory illness among young children
Read the following passage, then answer the question below. Museum labels rarely mention it, but a great many Renaissance paintings were produced by workshops rather than by individuals. A master would negotiate the commission, sketch the composition, and paint the passages that mattered most to the patron, usually faces and hands. Assistants filled in drapery, landscape, and architectural detail, often working from pattern books. Conservators using infrared imaging can now distinguish these hands with some confidence, and their findings have unsettled a market built on single attributions. Yet the workshop system was neither a shortcut nor a fraud. Contemporaries understood a painting as the product of a studio operating under a master's direction, and they judged it on the quality of the finished object. The notion that a painting's worth depends on one person having touched every square inch of it is a later invention. The passage is primarily concerned with:
Correct answer: A - how Renaissance workshops complicate modern ideas of authorship
Read the following passage, then answer the question below. Antibiotic resistance is often described as something bacteria acquire, but the genes involved are ancient. Sequencing of soil recovered from permafrost thousands of years old has turned up resistance genes closely resembling those found in hospitals today, long predating any human use of antibiotics. Many antibiotics are, after all, compounds that soil microbes evolved to suppress their competitors, and those competitors evolved countermeasures in turn. What human medicine changed was not the existence of these genes but their abundance. Heavy antibiotic use in clinics and livestock operations rewards the small fraction of bacteria already carrying resistance, allowing them to dominate a population within a few generations. The genes were always present; medicine supplied the selection pressure that made them common. The passage most strongly supports which conclusion?
Correct answer: B - Resistance would persist at low levels even without medical use of antibiotics
