During the last interglacial period

Post
During the last interglacial period, the climate on the Earth was warmer than it is today, and the consequent melting of the polar ice caps caused the sea level to raise about 60 feet over and above what its height presently is now.

A. sea level to raise about 60 feet over and above what its height presently is now
B. sea level to be raised over its height presently about 60 feet
C. sea level to rise about 60 feet above its present height
D. level of the seas to rise over and above its present height about 60 feet
E. level of the seas to be raised over their height, now about 60 feet

Please give clear explanation why other Options isn't correct?

Hello!

Let's start with the difference between raise and rise:

Raise: We use the verb "to raise" when talking about a person performing an action onto another person or thing. We can raise the temperature in our room by lighting a fire, raise a book over our head, or raise money for a charity.

Rise: We use the verb "to rise" when talking about an action a person or thing does to itself. We rise out of bed in the morning, the temperature rises during the summer months, and the stock market rises on good days. No one is doing these actions on their behalf - we, the temperature, and the stock market are acting alone.

Now that we know this, we can rule out answers A, B, and E. All of them use some form of "to raise," suggesting the sea level is being raised by some other force. It's not. The sea level rises on its own. No one is pushing a button to make it happen.

This leaves us with options C and D. Now we have to deal with singular/plural agreement.

D is incorrect because the phrase "its present height" is a singular phrase referring to "the seas," which is plural. "Its" and "seas" don't match up, so it's wrong. To fix it, you would have to change "its present height" to "their present heights."

C is our final option, and it's the correct one because the singular "its" is now referring to "sea level," which is also singular and matches up perfectly!

I hope this helps. I'm available if you'd like any follow up.
