Pаssаge B Trаumatic brain injuries are assоciated with cоgnitive decline later in life, and a sharper drоp in cognition as we age, a study of twins who served in World War II shows.There is robust research demonstrating a relationship between head injuries and cognitive impairment or dementia later in life, “but I do not know of any others that use a twin-study design,” said Holly Elser, an epidemiologist and resident physician in neurology at the University of Pennsylvania who peer-reviewed the study.The study published in Neurology on Wednesday found that individuals who had a traumatic brain injury were more likely to have lower scores on cognitive tests when they were about 70 years old.They were also more likely to have rapidly declining scores after their first test if they had multiple traumatic brain injuries, lost consciousness because of a head injury or were 25 or older when the injury happened.“Even if it’s just a single traumatic brain injury, we now know that it led to worse cognitive outcomes later in life,” said Marianne Chanti-Ketterl, the lead author of the study and an assistant professor in psychiatry and behavioral sciences at the Duke University School of Medicine.The study of identical and fraternal twins allows researchers to compare participants to each other while controlling for some, if not all, of the underlying genetic factors and some of the twins’ early life conditions. Identical twins share 100 percent of their genes, while fraternal twins share about half. Which of the following conclusions about head injuries can most reasonably be drawn from the passage?

[Nоte: Steve Wоnder аnd Rаy Chаrles, well-knоwn musicians of the 20th and 21st centuries, both lost their vision during early childhood.] Passage E The music of Stevie Wonder and Ray Charles supports the common belief that losing one sense can enhance another. Italian researchers have better evidence. They find that after only 90 minutes, blindfolded people can develop a keener sense of touch — a sign that the portion of the brain dedicated to vision can help process other senses. Although such neurological flexibility used to be considered a feature of a developing brain, "we know now that, even in adults, it is possible to find plastic interactions. If you change the input, you can recruit a part of the brain for a different function," says Salvatore Aglioti, a neurologist at the University of Rome La Sapienza and the Santa Lucia Foundation. Aglioti and a colleague asked 28 test subjects to place their fingers on a series of plates marked with grooves of varying sizes, with the width of the grooves equal to the distance between them. Some of the grooves were so fine that the surface of the plate felt smooth. After being blindfolded, however, people were able to feel grooves that were more subtle than the smallest ones they could discern in a previous test. Repeating the test 130 minutes after the blindfolds were removed, the subjects' sense of touch had reset to normal. "Forgetting is as important as learning," Aglioti says. "If we don't forget quickly, we don't have enough room for other functions." Which answer choice best reflects the text structure or overall organizational pattern of the passage?
Pаssаge C The centerpiece оf the student debt-relief plаn that President Biden annоunced last mоnth is his decision to cancel up to $20,000 per borrower in federal loans. But the more far-reaching — and, over time, more expensive — element of the president’s strategy is his blueprint for a revamped income-linked repayment plan, which would sharply reduce what many borrowers pay every month. It could, however, have unintended consequences. Unscrupulous schools, including for-profit institutions, have long used high-pressure sales tactics, or outright fraud and deception, to saddle students with more debt than they could ever reasonably hope to repay. By offering more-generous educational subsidies, the government may be creating a perverse incentive for both schools and borrowers, who could begin to pay even less attention to the actual price tag of their education — and taxpayers could be left footing more of the bill. “If people are taking out the same or more amount of debt and repaying less of it, then it’s just taxpayers bearing the brunt of it,” said Daniel Zibel, the chief counsel at the National Student Legal Defense Network, an advocacy group. Experts are particularly concerned about how the new subsidies could be manipulated by for-profit colleges, many of which have a record of persuading people to take on high debt for degrees that often fail to deliver the kind of earnings boost the schools advertise. The primary purpose of the passage is to
