Question

select the text from the paragraph that best helps you understand that deleterious means harmful. there may be more than one correct choice. some of these solar wind particles end up traveling in earths direction. if unimpeded, these particles would have deleterious effects on human health, increasing the risk of heart failure and other health problems. but earths magnetic poles—located near the geographic north and south poles—create a magnetic field that protects the planet from the solar wind particles. some of these particles, however, do manage to break free and end up colliding with oxygen and nitrogen in earths atmosphere. the collisions release energy, thus creating the auroras stunning display.

Explanation:

To understand "deleterious", we look at the context. The sentence says solar wind particles, if unimpeded, would have deleterious effects on human health (increasing heart failure and other health problems). The phrase "increasing the risk of...health problems" shows these effects are harmful, so "deleterious" means harmful. The relevant text is: "unimpeded, these particles would have deleterious effects on human health, increasing the risk of heart failure and other health problems."

Answer:

unimpeded, these particles would have deleterious effects on human health, increasing the risk of heart failure and other health problems.
