Question

Fill in the blank in the following sentence with the correct word from the alternatives: 
He solved all the questions with ____.

Accepted Answer

The correct answer is Option 4, "ease," because it forms a grammatically correct and idiomatic phrase with the preposition "with."

Here's a detailed explanation:

1.  **Why Option 4 (ease) is correct:**
    *   The word "with" is a preposition. Prepositions are typically followed by a noun or a pronoun to form a prepositional phrase.
    *   "Ease" is a noun, meaning "freedom from difficulty or effort."
    *   The phrase "with ease" is a common and grammatically correct idiom that means "easily" or "without difficulty." It correctly uses a noun ("ease") after the preposition ("with").
    *   Therefore, "He solved all the questions with ease" correctly conveys that he solved them without any difficulty.

2.  **Why Option 1 (easy) is incorrect:**
    *   "Easy" is an adjective. Adjectives modify nouns or pronouns.
    *   While you can say "an easy task," you cannot say "with easy" in this context. Prepositions are followed by nouns, not directly by adjectives in this manner to complete the phrase. "With easy" is grammatically incorrect.

3.  **Why Option 2 (easily) is incorrect:**
    *   "Easily" is an adverb. Adverbs modify verbs, adjectives, or other adverbs.
    *   While "He solved them easily" would be a correct sentence, "with easily" is grammatically incorrect. Prepositions are followed by nouns or pronouns, not adverbs.

4.  **Why Option 3 (easier) is incorrect:**
    *   "Easier" is the comparative form of the adjective "easy" or the adverb "easily."
    *   Like "easy" and "easily," it is not a noun. Therefore, it cannot correctly follow the preposition "with" in this construction. "With easier" is grammatically incorrect.
