Biological weathering is caused by living organisms, such as microbes, animals, and plants. Water, oxygen, and rocks are nonliving things (though water and rocks may be capable of weathering), and only plant roots fits the definition of biological weathering. So the correct answer for #1 is A.
Frost wedging occurs when the little water content in rock freezes, expanding and forcing the rock apart. Eventually, enough freeze-melt cycles causes the rock to break apart little by little. This is due to ice's density being less than that of water, meaning that it is because water expands when frozen. So the answer to #2 is A.

Supporting points are:
Help the disadvantaged,support the underdeveloped nations humanitarian departments such as health and security,help integrate the people into the global economy, especially through educational initiative.It is in line with the moral majority, and christian doctrines of humanity.Can help eradicate human rights abuses as aid is tied to such demands
AgainstMost of the funds get into a few african elites hands anyway Redirecting tax payers money into other nation is morally wrong.It defeats the essence of rationality, as the country gets little benefit by giving out the aid.
