Question

For reasons I have never been able to understand, a sudden demand for tamarind seeds erupted in the market. (a) came up (b) blew up (c) ended

Answer 1

(a)Came up.

EXPLANATION:

At the time of Second World War, the demand of tamarind seeds break out suddenly. Dramatically the need for tamarind seeds rise or came up. ‘blew up’ will not come in the above sentence. It is ‘blow up’ meaning  that explode . ‘ended’ will not come for the above sentence because it defines that ‘it is over’. So ‘came up ‘ will be suitable for the above sentence to complete it.
