Which of the following sentences is grammatically correct?

Question

Accepted Answer

Option 4, "He is making a determined effort to succeed in the examination," is grammatically correct. This sentence is structured properly, with a clear subject ("He"), a verb phrase ("is making"), and an object ("a determined effort to succeed in the examination"). The sentence effectively conveys the idea that the person is actively trying to achieve success in the examination through a focused and intentional effort.

Now, let's examine why the other options are incorrect:

1. "If you will run, you will catch the bus." 
   - This sentence is incorrect because it uses the future tense "will" in both clauses. In conditional sentences, the correct structure is to use the present simple tense in the "if" clause and the future simple tense in the main clause. The correct form should be: "If you run, you will catch the bus."

2. "He is more intelligent than either of his four brothers."
   - This sentence is incorrect because "either" is used when referring to two items or people. Since the sentence mentions "four brothers," the correct word should be "any," as in: "He is more intelligent than any of his four brothers."

3. "You should settle the dispute in amicable way."
   - This sentence is incorrect because it is missing an article before "amicable way." The correct form should be: "You should settle the dispute in an amicable way."

In summary, Option 4 is the only sentence that is grammatically correct, as it follows the proper sentence structure and uses appropriate language to convey its meaning.
