Reading the passage
Four answers describe changes that might help prevent premature heart disease, according to this account. One doesn't. We'll check what each change actually does; recognizing a scientific term won't be enough.
Working the answers
- ACorrect
Platelets are familiar, but the direction is wrong. The author treats reduced platelet adhesiveness as helpful because it means less tendency to form clots. A increases the degree of clotting instead. It reverses the improvement we were told about.
- B
The account connects high blood lipid levels with heart disease. Removing more lipids would address that problem, so this fits a potentially helpful change.
- C
This needs a closer look. The second paragraph accepts alcohol's harmful effects, then presents slower absorption from wine as a notable difference from spirits. In that context, taking longer to absorb it is offered as a possible part of the more favorable picture. The question only asks what might help, not what has been conclusively proved to prevent disease.
- D
The final paragraph describes increased activity of a natural clot-breaking compound, which doctors use to restore blood flow. That fits the proposed benefits.
- E
Increased compounds that may protect against damage from high lipid levels are expressly mentioned. A is the one that turns a helpful decrease into an increase.
