Paul farmer found poor rural haitian residents experiencing very high rates of malnutrition, dysentery, tuberculosis, and hiv/aids. many of these residents were water refugees due to the construction of a hydroelectric dam that provided water to cities and large landholders that had flooded their valley. this problem underlines the difficulty of providing adequate health care in the face of
a. rural development projects
b. socioeconomic inequality
c. globalization
d. a highly corrupt government

a)rural development projects,as it's arleady given as hint in the question

Option A

Explanation:

All multilateral funding agencies such as World Bank, Asian development bank and United Nations have formulated a strict social impact assessment and rehabilitation guidelines which are mandatory for all the urban and rural development projects. These projects can be started only when there are sufficient measures to cater the social and economic losses of local residents based on their vulnerability. However, inspite having such strict guidelines, effective measures are not being taken to eradicate such problem.  

Hence, option A is correct

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.
