It has been proposed that teenagers aged 10 to 15 years be restricted to less than 2 hours per day...

Understanding the Question

We need to determine whether a significant number of teens aged 10-15 would get an overall developmental or health benefit from restricting social media to less than 2 hours per day.

This is a yes/no question. We need to determine if we can definitively answer YES (they would benefit) or NO (they would not benefit).

What We Need to Determine

To answer this question with certainty, we need information that allows us to:

• Understand the impacts (both positive and negative) of 2+ hours of social media use
• Evaluate the overall effect (weighing benefits against harms)
• Determine if the number affected qualifies as "significant"

The key word here is "overall" - we must consider both benefits and drawbacks to reach a definitive conclusion.

Analyzing Statement 1

Statement 1 tells us that teens who use social media for 2+ hours per day experience a 23% increase in chronic anxiety or depression.

What Statement 1 Tells Us

• There's a clear negative health impact from 2+ hours of social media use
• The 23% increase in anxiety/depression is substantial
• This suggests restricting usage might reduce these mental health issues

What We Don't Know

However, Statement 1 only gives us one side of the story:

• We don't know if there are any benefits from 2+ hours of social media use
• We can't determine the overall impact without knowing both positives and negatives
• We don't know what percentage of teens are affected (the 23% is an increase rate, not the percentage of teens affected)

Since we cannot determine the overall benefit (which requires weighing all factors), Statement 1 alone is NOT sufficient.

[STOP - Not Sufficient!]

This eliminates choices A and D.

Analyzing Statement 2

Now we forget Statement 1 completely and analyze Statement 2 independently.

Statement 2 reveals that 28% of teens who use social media for 2+ hours per day develop meaningful friendships and gain social/emotional learning benefits.

What Statement 2 Provides

• Clear developmental benefits for a specific percentage (28%) of teens
• These benefits include meaningful friendships and social/emotional learning
• These are explicitly valuable for development at ages 10-15

The Key Logical Insight

Here's the crucial reasoning: If 28% of teens gain important developmental benefits from 2+ hours of social media use, then restricting them to less than 2 hours would remove these benefits.

This means that for these 28% of teens (certainly a "significant number"), the restriction would NOT provide an overall benefit - it would actually harm their development by cutting off valuable social connections and learning opportunities.

Conclusion

We can now definitively answer NO to the question. A significant number of teens (at least 28%) would NOT get an overall benefit from the restriction because they would lose important developmental opportunities.

Statement 2 alone is sufficient to answer the question with a definitive NO.

[STOP - Sufficient!]

This eliminates choices C and E.

The Answer: B

Statement 2 alone allows us to definitively answer NO - a significant portion of teens would actually be harmed by the restriction, not benefited.

Answer Choice B: "Statement 2 alone is sufficient, but Statement 1 alone is not sufficient."
