Political parties are to express the wishes of the people.

I believe the answer is: Instruments

The role as instruments mean that political party could be used as some sort of tools that the people use to get their aspiration across the government body. This is why politicians are considered to be 'public servants', because they inherently exist to fulfil the will of the people.

muslims have taken his goods and products to different parts of asia an indonesia. sometimes just traveled and trade, but in other occasions, stayed in the place and made a living.

trade was the key for muslims economies to prosper. their commerce routes reached far places like malaysia and java in the 11th century.

another important factor for prosperity was that muslim states served as the middle point for european traders.

they used to travel by land but sailing the seas -the indian ocean- really increase the exportation of products.
