Ocean Warming

From Twitter:

Scientists said today that the oceans are __ so quickly it’s like 5 atomic bombs are being detonated in the sea.

a. heated
b. heats
c. heating
______

It’s a serious problem, so please turn off your car, scooter or truck when not driving and all electricity at home when not using it.

Answer: c., heating

Explanation:

Technically, t
here are two possible grammatical answers but only one contextual correct answer; a., heated is possible grammatically, but in context would make no sense, because using the past tense in this way indicates the causative, meaning someone or something heats the ocean, which of course we know is not true (unless we are talking about the sun); the ocean is heated naturally; people could split hairs with me on this, and they would be right, but give me a break; I’m trying to make a more important point:

The sentence begins with ‘scientists said today…’ and ‘are’ is the linkning verb, so–the best answer is heating (are + ing = the present continuous)

Prepare

The Answers Are: prepares (a), preparing (c), prepared (a)

Explanation:
After ‘always’, a simple tense verb, we can have a past tense or a present tense verb. If we look at the end of the sentence, we see ‘we always have a wonderful time’, meaning this is the present, not the past–so we need a present tense verb after always–so the answer to the first option is ‘prepares’.

After ‘by’ we need a gerund, because by introduces nouns of process or conveyance and actual things; think of how we say ‘go by train’, ‘solve the problem by using calculus’, the cat reached the window by jumping.

After ‘is always’ we need an adjective form or a continuous verb form, because ‘is’, a linking verb, and ‘always’ as an adverb require a description or a habitual action, but the choices offer only one ‘ing’ option and it is needed elsewhere!
