A study comparing infant care revealed that the amount of stimulation babies receive affects their sleep.
Conclusion
Parents would be wise to reduce the amount of stimulation their babies receive.
Evidence
A study shows that babies with a less stimulating daytime routine slept an average of two hours more per day than those with a more stimulating routine. Since sleep plays a very important role in a child's development, it is suggested that reducing stimulation would be beneficial.
Evaluate
This is a "Weaken" question where we want to find an answer choice that challenges the conclusion that reducing stimulation is wise. We should look for reasoning or evidence that highlights the potential benefits of maintaining or even increasing stimulation, which might outweigh the benefits of additional sleep.
Goal
Identify an answer choice that illuminates a reason why stimulation might still be important, despite its impact on sleep, thus challenging the conclusion that reducing stimulation is beneficial.
Conclusion
Choice E effectively weakens the argument by highlighting that stimulation contributes to intellectual development. It introduces important developmental benefits that could balance or outweigh the advantage of increased sleep, directly challenging the advice to reduce stimulation. The other options either do not directly impact the argument or indirectly support it.
