As surprising as it may seem, in the medium

OFFICIAL SOLUTION

When you look at the first word in each answer option, you can quickly deduce that this question is about a singular / plural issue.

Next, notice the presence of the relative pronoun “that” in the question. The most important relative pronouns for our purposes are “who”, “which” and “that”. In this case, the rule is that the verb that follows the relative pronoun must agree in number with the word that comes immediately before the relative pronoun. Notice in this sentence that the word “places” comes before the relative pronoun “that”. Therefore, the verb that follows the relative pronoun must be plural to agree with “places”. This is because of the special construction “one of the + plural + relative pronoun”.

Now that you know the verb following the relative pronoun must be plural, you can eliminate answer options B and D.

Notice how answer option C changes the meaning of the original sentence. 'Likely' is not the same as 'most likely'. So, you can eliminate C.

The elimination of the preposition “from” in answer option E changes the meaning of the original sentence completely. Therefore, eliminate E.
That leaves only one option: A is correct.

In summary, remember the important rule that in the special construction “one of the + plural + relative pronoun” the verb that follows the relative pronoun agrees in number with the word that comes immediately before the relative pronoun. The verb is therefore plural. Remembering such relatively simple rules will make you feel more secure about sentence correction and will allow you to spend more time on other more difficult questions.

As surprising as it may seem, in the medium-long term Iceland is one of the places that are most likely to benefit from global warming.

a, are most likely to benefit from
