Question

I shall have written my exercise _ _ _ _ \(6\) pm.

• A. until
• B. by
• C. to
• D. in

Hint:

Use \(by\) with future perfect tense to show completion before a fixed time.

Answer 1

The Correct Option is B

Concept:
The phrase \[ \text{shall have written} \] is future perfect tense. Future perfect tense is used to show that an action will be completed before a certain time in the future. The preposition used for completion before a deadline is \[ by \]

Step 1: Identify the tense. \[ \text{I shall have written} \] This is future perfect tense.

Step 2: Identify the time expression. The time expression is \[ 6\text{ pm} \] The action will be completed before or at \(6\) pm.

Step 3: Choose correct preposition. The correct preposition is \[ by \] So the sentence becomes: \[ \text{I shall have written my exercise by 6 pm.} \]

Step 4: Final answer. \[ \boxed{\text{by}} \]
