Subject-Verb Agreement:
The subject "She" is singular, and the verb "gave" agrees with the subject.

Adverb of Manner:
The adverb "kindly" is used to describe how the person gave the birthday present.

Direct Object:
The direct object "me" receives the action of the verb "gave."

Indirect Object:
The indirect object "birthday present" is what was given to the person.

Corrected Sentence:
"She kindly gave me a birthday present."

In conclusion, the sentence "I lonely walked around the park" is incorrect due to subject-verb agreement. The correct sentence should be "I walked alone around the park."

The correct answer is A: "I lonely walked around the park."
Explanation:
The sentence "I lonely walked around the park" is not grammatically correct. Here's a breakdown of the errors:
1. Use of incorrect adverb: "lonely" is an adjective, not an adverb. The correct adverb form is "lonelily" or "alone."
2. Incorrect word order: The word order in the sentence should be "I walked around the park lonely" or "I walked alone around the park."
The other two sentences are correct:
- B: "We arrived at the school early." This sentence is grammatically correct, stating that the subject "we" arrived at the school before the expected time.
- C: "She kindly gave me a birthday present." This sentence is also grammatically correct, indicating that the subject "she" gave the speaker a birthday present with kindness.
In summary, the incorrect sentence is A because of the incorrect use of an adjective instead of an adverb and the incorrect word order.
