I believe the question is:
<em>"What were the causes and impact of increased Indian ocean trade in Post-Classical era?"</em>
Explanation:
Some of the causes of the increased Indian ocean trade during the Post-Classical era were<em> the increase volume of trade, the tremendous number of people involved and the various interactions happening from culture to culture.</em> The increase in the volume of trade was mainly due to the in<u>fluence of the Islam religion</u> which allowed the Muslim city-states to participate in the maritime trading. This then increased the items such as <em>gold, ivory and exotic animals</em> coming from southern Africa and the sub-Saharan. Due to new maritime technologies such as the compass and the used of "Junks" <em>(big trading ships</em>), larger cargoes could be transported and this assisted a faster way of trading in bulks. The "astrolabe" <em>(a celestial sphere)</em> was also introduced and this aided the sailors, especially in <em>preventing the</em><em> risks of maritime trade</em>.
