Explanation:

Required

Complete the gaps

(a) Flying cars more popular in the future (be)

The sentence here refers to what will happen at a later time. However, the statement is an imagination of what is to happen and not what will happen.

So, the blank will be completed with would be.

"would be", as used, means flying cars will most like be popular.

(b) The next train at 9a.m (leave)

The sentence here refers to what will happen at a later time; and it is certain that the event will happen.

So, the blank will be completed with will be.

"will be", as used, means the train will definitely leave once it's 9am.

(c) Don't visit me next month! I In Greece. (travel)

Here, we have two blanks.

The first will be completed with "I will be travelling" as implied with the word in bracket.

The second statement supports the first; and it shows where the person would be, "next month"

So, we complete the statement with "I will be"
