Let's look at the specific instructions in the paper.

Q.6 (a) Explain the difference between the following word pairs (Any FIVE) by using each word in your own sentences:
(b) Use ONLY FIVE of the following in sentences which illustrate their meaning:

They have not asked for meanings at all. The instructions are fairly clear; Use the words in a sentence so that their meaning becomes clear. What this means is sentences like "this is a nice dinghy" are not acceptable. It is a complete sentence on its own using one of the pair of words from 2017, but in the sentence it is not clear WHAT or WHO a dinghy is. A better sentence with the same word would be, "Their small dinghy was unable to stay afloat when the storm suddenly hit." This clarifies the meaning of the word so that even if someone has never read or heard about this word before they now know that Dinghy are sea-vessels of some sort just by reading the sentence. I hope this clarifies your query
