Answer:
a) Migrant workers send monies as gifts to their relatives in their home countries, they increase the purchasing power of their relatives. More money equals more purchasing power. This purchasing power is futher magnified by the (in many cases) huge difference in purchasing power between the currency in the migrants home country and the country of temporary residence.
b) migrant workers send remittances in order maximize the added purchasing power afforded by the huge variances in exchange rate. These monies sometimes are gifted to family members to help them or for some other project to be executed on behalf of the migrant.
c) the money is either used by the recipient for their own purposes in the case of a gift or used for the execution of a project on behalf of the migrant. Projects may include setting up a business, building a house or purchasing a property etc.

The correct answer is (2)
The moon's rotational period was wasn't always equal to its orbit (revolution) around the planet. Just like gravity of the moon affects ocean tides on the earth, gravity from earth affects the moon. But because the moon lacks an ocean, earth pulls on its crust, creating a tidal bulge at the line that points toward earth.
Gravity from earth pulls on the closest tidal bulge, trying to keep it aligned. This creates tidal friction that slows the moon's rotation. Over time, the rotation was slowed enough that the moon's orbit and orbit and rotation matched, and the same face became tidally locked forever pointed toward earth.
