Fill in the blank with the appropriate adjective:
We decided to meet since both of us had _______ time to spare.
The adjectives ‘few’, ‘a few’, ‘little’ and ‘a little’ are used to denote quantity. ‘A few’ and ‘a little’ mean some, whereas ‘few’ and ‘little’ mean hardly any. ‘A few’ and ‘few’ are used for countable nouns. On the other hand ‘a little’ and ‘little’ are used for uncountable nouns. As ‘time’ is an uncountable noun, we cannot use ‘a few’ or ‘few’. Hence option A and B are incorrect. ‘Little’ means hardly any, and it is used only in negative sentences to convey the complete lack of something. Since the sentence states that there is some time to spare option C is incorrect. ‘A little’ means some, which conveys a positive meaning. As mentioned above, the speaker and his/her friend have some time which can be spared to meet each other, therefore ‘a little’ is the apt answer. Thus option D is correct.
