[EX Q]: Context: After a win at Cleveland, the Steelers traveled to Baltimore to take on the Ravens in what would be the Thanksgiving Primetime Game and of course their first game on Thanksgiving Day since 1998. The Ravens drew first blood as Joe Flacco found Torrey Smith on a 7-yard pass to make the score 7-0 in the first quarter. In then 2nd quarter, Justin Tucker nailed a 43-yard field goal for a 10-0 halftime lead. After the break, the Ravens went back to work in the 3rd quarter as Tucker nailed a 34-yard field goal for a 13-0 lead. The Steelers finally got on the board asBen Roethlisberger found Emmanuel Sanders on an 8-yard touchdown pass for a 13-7 score. The Ravens then pulled away as Tucker kicked yet another field goal putting his team ahead by 9, 16-7. In the 4th quarter, Tucker kicked yet another field goal this one from 45 yards out for a score of 19-7. The Steelers managed to draw within 5 points 19-14 when Le'Veon Bell ran for a 1-yard touchdown. Tucker then kicked a 48-yard field goal to make the score 22-14.

[EX Q]: Context: The apolipoprotein E type 4 allele is a susceptibility gene for late-onset Alzheimer's disease. Apolipoprotein E is found in neurons, some of which contain paired helical filaments made of the microtubule-associated protein tau. Previous studies have demonstrated that the apoE3 isoform, but not the apoE4 isoform, binds tau with high avidity. Because the microtubule-associated protein MAP2c also effects microtubule assembly and stability, we examined interactions between apoE isoforms and MAP2c. Similar to the tau-binding results, apoE3, but not apoE4, bound MAP2c. Binding was detectable down to 10(-9) M MAP2c and 10(-8) M apoE3. Isoform-specific interactions of apoE with the microtubule-associated proteins MAP2c and tau might affect intracellular maintenance of microtubules and could contribute to a time-dependent pathogenesis of Alzheimer's disease. 
 Question: Which ApoE isoform is associated with atherosclerosis and Alzheimer's disease?
[EX A]: apoe4 isoform
