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 earth’s direction. if unimpeded, these particles would have deleterious effects on human health, increasing the risk of heart failure and other health problems. but earth’s 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 earth’s atmosphere. the collisions release energy, thus creating the aurora’s stunning display.

Explanation:

To understand that "deleterious" means harmful, we look for text that shows negative impacts. The phrase "increasing the risk of heart failure and other health problems" describes the effects of the unimpeded solar wind particles, which are the "deleterious effects" mentioned. This shows the effects are harmful as they increase health risks. Also, "Earth’s magnetic poles... create a magnetic field that protects the planet from the solar wind particles" implies the particles have harmful (deleterious) effects that need protection from.

Answer:

• increasing the risk of heart failure and other health problems
• Earth’s magnetic poles—located near the geographic North and South Poles—create a magnetic field that protects the planet from the solar wind particles
