The correct answer to complete the sentence ".

They had a big house and AT THE BACK OF it there was a small lake"

would be: A) behind

Explanation: "At the back of" implies something located behind or to the rear of something else.

Option A ("behind") directly conveys this meaning.

Options B ("in front of"), C ("between"), D ("over"), and E ("near") do not appropriately describe a location at the rear of something.

Therefore, Option A ("behind") is the best choice to complete the sentence naturally.

The correct answer to complete the sentence

"TWO HUNDRED YEARS ago the square yard was very clean" would be: C) two centuries Explanation: "Two hundred years" is equivalent to "two centuries."

Option C ("two centuries") accurately represents the time frame mentioned in the sentence.

Options A ("many years"), B ("two weeks"), D ("a fortnight"), and E ("two months") do not match the specific duration of two hundred years.

Therefore, Option C ("two centuries") is the correct choice to complete the sentence naturally.

Options A ("take"), C ("revise"), D ("copy"), and E ("hold") do not fit the context of returning the book.

Therefore, Option B ("return") is the best choice to complete the sentence naturally.

Explanation: "Began" and "started" are synonyms, both indicating the initiation of an action or activity.

Option D ("started") fits naturally in the context of beginning to work together.

Options A ("finished"), B ("stayed"), and C ("continued") do not convey the same meaning as "began" or "started."

Therefore, Option D ("started") is the best choice to complete the sentence naturally.

The correct answer to complete the sentence

Explanation: "Began" directly indicates the start of an action, in this case, shouting.

Option C ("started") fits naturally with the context of the sentence where the action of shouting begins.

Options A ("finished"), B ("stopped"), D ("set"), and E ("was over") do not convey the beginning of an action as required by the sentence.

Therefore, Option C ("started") is the correct choice to complete the sentence naturally.

The correct answer to complete the sentence

Options A ("solved"), B ("decided"), and C ("understood") do not fit the context of describing an event or incident that has occurred.

Therefore, Option D ("taken place") is the best choice to complete the sentence naturally.
