Question

I ........ the success of our plan (doubt,suspect)​

Answer 1

Answer:

I suspect the success of our plan.

Answer 2

1. 'Doubt' means you believe something is false.
2. 'Suspect' means you believe something may or may not be true, especially if others are telling you otherwise.
3. What you believe is 'suspect', but what you disbelieve is a 'doubt'.
4. Basically, you are doubtful of the plan, not suspicious of it.
5. Thus, the most appropriate word to fill the blank is 'doubt'.

Hence, the correct sentence is-

I doubt the success of our plan.
