Explanation

Show analysis

Coffee and tea contain methylxanthines, which cause temporary increases in the natural production of vasopressin, a hormone produced by the pituitary gland. ███████████ ██████ ████████ ██ █████ ██████ ███ ███ ████████ ██ ████ ██████████ ██ █████ ████ ██ ████ ████ ██ ████████ ███ ███████████ ██ ███ ████ ████ █████ ████ ██ ████ ██ █ ███████ ██████ ████ ████ ███ ██ ██ █████████████ █████████ ████████████ █ █████████ ████ ██ █████ ███████ █████████

Summary

Coffee and tea contain a substance (methylxanthines) that leads to temporary increases in the body’s production of vasopressin. Vasopressin causes clumping of blood cells, and this clumping is more pronounced in women than in men. Increased clumping of blood cells is probably why, compared to men, women have a significantly higher risk of complications following angioplasty, which is an operation for clearing clogged arteries.

Strongly Supported Conclusions

In at least one respect, coffee and tea may be more dangerous to women than to men.

Drinking excessive amounts of coffee or tea may lead to increased risk of complications following angioplasty.

Which one of the following ██████████ ██ ████ ████████ █████████ ██ ███ ███████████ ██████

Men, but not ██████ ██████ ██ █████ ███████████████ █████ ██ ██████████ ████████████

Unsupported. We’re not given a reason anyone should be given methylxanthines ever. Maybe there’s nothing positive about methylxanthines.

In spite of ███ ██████ ███████████ ██ ███ ████ █████████ █████████ ███ ███████ █████████

Unsupported. We’re told angioplasty is one technique for unclogging arteries, but we don’t know whether there are any other techniques that could be effective.

Women probably drink ████ ██████ ███ ████ ██ ████████ ████ ██ ████

Unsupported. The stimulus tells us about the effects of coffee and tea, but not about the number or proportion of men or women who drink coffee and tea.

Prior to undergoing ████████████ █████ ██████ █████ ██████ ███ ████

Strongly supported. Women face a higher risk of complications following angioplasty because clumping of blood cells is more pronounced in their bodies. Since coffee/tea increase substances that lead to clumping, there’s reason for women to avoid coffee/tea before angioplasty.

Unsupported. Angioplasty may lead to complications, but that doesn’t imply that the technique is not worth the risk of complications.
