Let's analyze the question to determine the correct grammatical usage in the given sentence.
Given Sentence: You are a great deal more sociable than him.
The sentence contains a comparative structure, where it compares "You" with "him" in terms of sociability.
- The underlined portion "than him" is where we need to check for correct grammatical usage.
- In English grammar, when making comparisons using "than," the pronoun following "than" should be in the subject case (nominative case) and should imply the verb "to be" if not explicitly mentioned.
- Hence, in the comparative structure, it should be "more sociable than he is."
Let's evaluate the options:
- Option 1: more sociable than he is - This option is correct. It follows the standard English grammar rule of using the subject pronoun "he" and completes the comparison structure with the implied verb "is."
- Option 2: more sociable than him - This option is incorrect because "him" is an object pronoun and does not fulfill the grammatical requirement of a subject pronoun in this comparison.
- Option 3: more social than he - This option is incomplete as it lacks the implied verb, although it correctly uses the subject pronoun "he."
- Option 4: No change - This is incorrect as the original underlined phrase uses "him," which is grammatically incorrect.
Therefore, the correct answer is "more sociable than he is".
