Question

fill in the blank? i __ (swim) across the river when I was young. (a) could (b)should(c)shall (d)would​

Answer 1

The blank can be filled as follows:

I would swim across the river when I was young.

• The sentence in the question depicts an action which took place in the past.
• Using other options like, option c, is not correct because if 'shall' is used to fill the blank, then the sentence no longer gives a 'past' meaning to the structure of the sentence.

Hence, the best option to fill in the blank is d) would.
