Question

read this excerpt from the text and one from another source. what does the second excerpt explain about the first?
a how much salt the treatment plants add to seawater
b the reason seawater treatment plants are not a good solution to droughts
c how much untreated seawater a human could drink
d the effect drinking untreated seawater would have on humans
excerpt 1 excerpt 2
seawater contains salt. when humans drink seawater, their cells are thus taking in water and salt. while humans can safely ingest small amounts of salt, the salt content in seawater is much higher than what can be processed by the human body.

Explanation:

Excerpt 2 focuses on the impact of drinking seawater (which has high salt content) on human cells and the body's inability to process that much salt. It's about the effect on humans. Option A is wrong as it's not about treatment plants adding salt. Option B is incorrect as it's not about drought solutions. Option C is wrong as it's not about the quantity a human could drink. Option D aligns with the content of Excerpt 2.

Answer:

D. the effect drinking untreated seawater would have on humans
