In the question below, a paragraph is split into several parts. Examine each part for grammatical accuracy and select the option that correctly identifies which parts are grammatically correct or incorrect.

(A) Although scrolling late at night reduces attention spans, it also disrupts sleep cycles. By share personal details carelessly, (B) users risk exposing themselves to scams. Constantly comparing oneself with influencers (C) often leads to envy and poor body image. People spend hours watching short videos, (D) so they neglect to study and exercising. Because many posts are exaggerated, (E) fact-checking before sharing is essential.

The correct answer is B, C and E are correct.

Let us analyze each part of the given paragraph for grammatical accuracy:

Part (A): "Although scrolling late at night reduces attention spans, it also disrupts sleep cycles. By share personal details carelessly,"
Analysis: The second sentence contains a grammatical error in the prepositional phrase. The preposition "By" must be followed by a gerund ("sharing") rather than the base verb "share" (i.e., "By sharing personal details carelessly"). Therefore, Part (A) is grammatically incorrect.

Part (B): "users risk exposing themselves to scams. Constantly comparing oneself with influencers"
Analysis: This part is grammatically well-formed, using appropriate subject-verb agreement and proper reflexive pronoun usage. Therefore, Part (B) is grammatically correct.

Part (C): "often leads to envy and poor body image. People spend hours watching short videos,"
Analysis: The verb "leads" correctly agrees with the singular gerund subject phrase "Constantly comparing oneself", and the subsequent sentence structure is sound. Therefore, Part (C) is grammatically correct.

Part (D): "so they neglect to study and exercising. Because many posts are exaggerated,"
Analysis: In the phrase "neglect to study and exercising", parallel structure is broken. The infinitive verb "to study" requires parallelism with the infinitive form "to exercise" or simply "exercise" (i.e., "neglect to study and exercise"). Therefore, Part (D) is grammatically incorrect.

Part (E): "fact-checking before sharing is essential."
Analysis: The gerund subject "fact-checking" correctly takes the singular verb "is", and the sentence is completely accurate. Therefore, Part (E) is grammatically correct.

Conclusion: Parts B, C, and E are grammatically correct, while parts A and D are incorrect.
