[EX Q]: Something strange was unbelievable. Take Robert for example. After the terrible car accident, his whole world had been completely dark and quiet for almost ten years. The loss of sight and hearing made him try many times to put end to his life. His family especially his wife did their best to tend and comfort him. By and by he finally regained the courage to live on. On a hot summer afternoon he was taking a walk with a stick near his house when a thunderstorm started suddenly. He stood under a large tree in order not to get himself wet. Unfortunately he was struck down to the ground by a lightning. The witnesses thought him dead but he woke up some 20 minutes later lying face down in muddy water below the tree. He felt that he was trembling badly, but when he opened his eyes ,he didn't dare to believe that he saw a plough( )lying near the wall. When Mrs Edwards came running up to him, she shouted their neighbours for help. And he saw her and heard her voice for the first time in nearly ten years. The news of Robert's regaining his sight and hearing quickly spread in his area. And many doctors came to prove the truth of the news. Most of them said that he gained sight and hearing again obviously from the knock of lightning; none of them could give convincing reasons, however. The only reasonable explanation given by one doctor was that, since Edwards lost his sight and hearing as a result of sudden shock in a terrible accident, perhaps the only way for them to regain was by another sudden shock.
[EX A]: What did Edwards see first after being struck down by a lightning?

[EX Q]: Three isoforms of human plasma apolipoprotein E (apoE) are ligands to lipoprotein receptors and influence in different manner the synthesis and catabolism of pro-atherogenic triglyceride-rich lipoproteins. Among three isoforms, the apoE4 isoform is associated with increased frequency of atherosclerosis and Alzheimer's disease (AD). The conformational transitions of beta-amyloid (Abeta) influenced by apoE and serum amyloid P (SAP) component are key events in AD development, the accumulation of intermediate diffusible and soluble oligomers of Abeta being of particular significance. SAP and apoE, in a different manner for the three isoforms, serve as "pathological" chaperones during the aggregation of Abeta considered as a conformation-prone process. In turn, apoE consisting of two domains self-associates in solution and intermediate structures differently populated for the three isoforms exist. The different structures of the three isoforms determine their different distribution among various plasma lipoproteins. The structural and metabolic consideration of the common apoE pathway(s) in two pathologies assumes four molecular targets for AD correction: (i) inhibition of the accumulation of diffusible soluble Abeta oligomers; (ii) inhibition of apoE synthesis and secretion by astrocytes, in particular, under lipid-lowering therapy; (iii) inhibition of the binding of apoE and/or SAP to Abeta; (iv) stimulation of the expression of cholesterol transporter ABCA1.
[EX A]: Which ApoE isoform is associated with atherosclerosis and Alzheimer's disease?

[EX Q]: On countless mornings over the past year, I stood with my son, James, in our driveway, watching our neighbor hurry off to kindergarten.My wife and I wanted to give James the best education, but that meant we'd have to change our jobs and spend less time with our kid.I asked myself, "Would this trade-off be worth it?" When I look at the research on child development, I think it might not.Where our kids go to school might matter less than most American parents think. Social scientists have long tried to determine why some children grow up to be successful.In a 2001 study, Greg Duncan, a professor of education at the University of California, measured the influence that the people in a child's life have on how well the child does in school.Duncan and his team found almost no relationship between how students did on the test and whom they sat beside in class, whom they hung out with after school and who lived in their block.The only meaningful link they found was between siblings and twins in particular. For a long time, scholars thought that a family's income heavily affected how well kids did in life.But that might not be the case.When Susan Mayer at the University of Chicago looked at the relationship between family income and lifetime achievement, she ran a series of experiments to measure it, finding such outcomes weren't caused by income.She argued that the things that make a difference are relatively inexpensive: the number of books a kid has or how often his family goes to museums. Lareau, another scholar began one of the most in-depth observations of American parenting.He concluded that success is much more related to the amount of time parents spend with their children.He said "Many parents I interviewed are anxious about their children's futures.But they have exaggerated the sense of the risks involved if they don't give their children 'the best' of everything." So at last, we decided to leave things as it were.More time with our kid is the best we can provide.

Who believes children's brothers and sisters may influence their academic performance?
