Rationale: High doses of caffeine contained in coffee and tea have been linked to an increased risk of low birth weight. Consuming large amounts of caffeine during pregnancy can interfere with the baby's growth and development, leading to a lower birth weight than expected. It is important for pregnant women to limit their caffeine intake to reduce the risk of complications such as low birth weight.

Correct Answer: C

Rationale: In the historic experiment with 11-month-old Albert conducted by John Watson, it was demonstrated that children can be conditioned to fear a formerly neutral stimulus. This is known as classical conditioning, where a neutral stimulus is repeatedly paired with an unconditioned stimulus to create a conditioned response. In this case, Albert was conditioned to fear a white rat by pairing the rat with a loud noise. This experiment showcased the power of conditioning in shaping behavior and emotional responses in children.
