Fill in the blanks with suitable prepositions.
They wanted to cut the cake _______ midnight. But time was moving slow. It was ten _______ twelve.
The preposition ‘to’ is used to refer to the time that is left for the beginning of something. In the given sentence there are ten minutes for it to become twelve. Hence ‘to’ is the apt answer for the second blank. On the other hand, ‘at’ is used to refer to an exact rate, speed or price at which something increases or begins, which is not apt here because the sentence doesn't speak about a rate, speed or price. Hence option B is incorrect. Whereas ‘on’ cannot be used in the first and or second blank because ‘on’ is a preposition of time that refers to a day or date. Thus option D is incorrect. We use the preposition ‘at’ while indicating an exact time like ‘midnight’. 'To' as mentioned earlier denotes the time left to do something which is not apt in the first blank since the sentence provides an exact time. Therefore option A is correct while option C is incorrect.
