In the question below, fill the gap with the most appropriate option:
The carpenter asked for ten packets of _____ nails
Answer Details
The most appropriate option to fill the gap is "fifteen-centimetre" without an apostrophe after centimetres. This is because the sentence is describing the length of the nails that the carpenter requested, and in this case, the length is expressed in terms of centimetres. The hyphen between "fifteen" and "centimetre" is used to indicate that these two words together form a single adjective that describes the type of nails required. An apostrophe after "centimetres" would indicate possession or ownership, which is not appropriate in this context.
