The slave trade became prominent along the Indian Coast. Where were most of these
slaves sent?

Hope this helps

Explanation:

The Indian Ocean slave trade, sometimes known as the East African slave trade, was the multi-directional slave trade and has changed over time. Africans were sent as slaves to the Arabian Peninsula, to Indian Ocean islands (including Madagascar), to the Indian subcontinent, and later to the Americas.

what are local authorities doing to fix the problem

explanation:

the hyksos invasion. the hyksos were able to attack egypt successfully because of their skills in using bronze weapons, composite bows and the use of the horse and chariot during the invasion. although the egyptians depict a barbarian-type overthrow, the truth is the seizure was likely a relatively peaceful one.
