Question 3

The Silk Road was a trade route that originated in China (specifically from regions producing silk) and extended westward to the Mediterranean Sea, facilitating trade with regions like Europe. Option A aligns with this historical fact. Options B (originating in India), C (Rome to Russia), and D (Rome to Japan) are incorrect as they don't match the known origin and destination of the Silk Road.

The silkworm (Bombyx mori) life cycle starts with an egg. The egg hatches into a larva (caterpillar/silkworm), which then enters the pupa stage (inside a cocoon), and finally emerges as an adult moth. Option D (Egg, larva, pupa, moth) follows this correct sequence. Option A incorrectly includes "cocoon" as a separate stage (cocoon is the structure of the pupa stage). Option B skips the pupa stage. Option C has an illogical sequence.

Answer:

A. China to the Mediterranean Sea
