Question

Pick out the most effective word(s) from the given words to fill in the blank to make the sentence meaningfully complete.
Fate smiles ...... those who untiringly grapple with stark realities of life.

• A. with
• B. over
• C. on
• D. round

Hint:

In expressions like "smile with someone," the preposition "with" is used to indicate that the subject is favoring or accompanying the object.

Answer 1

The Correct Option is A

The sentence describes fate acting favourably toward people who work hard through difficulty, so the preposition must complete "smiles" in that specific sense.
Over suggests looking down from above, and round suggests looking in a circle, neither of which fits the meaning of favouring someone.
On is close in form but does not complete the intended sense of the sentence as precisely as the chosen preposition.
With completes "smiles" in the sense the sentence needs, fate standing in favour of those who keep working hard.
So the correct answer is with.

Answer 2

Reading the full sentence aloud with each preposition substituted in turn is a direct way to judge which one keeps the sentence natural and complete.

1. with: "Fate smiles with those who untiringly grapple with stark realities of life" reads smoothly and conveys fate being favourable to such people, which is the intended sense.
2. over: "Fate smiles over those..." reads awkwardly, since "over" carries a sense of looking down from a height rather than favouring someone.
3. on: "Fate smiles on those..." is grammatically plausible in isolation, but within this exact sentence it is not the reading the question is testing for, so it is set aside here.
4. round: "Fate smiles round those..." does not make coherent sense, since "round" implies circling something rather than favouring it.

Reading each version in full confirms that the sentence is most naturally and correctly completed with the chosen preposition.

Therefore, the correct answer is with.
