Read the passage and answer the following question:
In an era dominated by digital devices, regulating children's screen time has become an increasingly complex challenge for parents and educators alike. While screens have revolutionized the way information is accessed and shared, excessive usage can have detrimental effects on young minds. Numerous studies have indicated that unregulated screen exposure may contribute to sleep disturbances, reduced academic performance, and impaired social interaction skills.
Conversely, when used responsibly, digital tools can foster learning, creativity, and global awareness. Hence, experts advocate for a balanced approach, emphasizing the need for clear guidelines and open dialogue between parents and children. Encouraging offline activities, monitoring content, and setting time limits are some strategies recommended to ensure that technology acts as an aid rather than an impediment to a child's development.
Which of the following sentences from the passage contains a present perfect tense verb?
Show answer & explanation
Correct answer: A
Explanation
The present perfect tense is formed by the auxiliary verb 'have' or 'has' followed by the past participle of the main verb (e.g., has become, have revolutionized, have indicated).
In option A, the verb is 'has become' (has + past participle of become), which is a present perfect tense verb.
In option B, the verb is 'have revolutionized' (have + past participle of revolutionize), which is also a present perfect tense verb. But, option ‘B’ also has passive past tense (is accessed and shared).
Therefore option ‘A’ is the correct answer.
