Humans affect the water cycle in numerous ways. Some of our actions purposefully affect the water cycle and other human activities have unintentional consequences on the water cycle.We pull water out of the ground in order to use it. We change the flow of water using irrigation. We dam lakes and rivers for electricity and to create manmade lakes and ponds. The Colorado River in the US no longer reaches the ocean at times because humans have altered it so much.Climate change is causing numerous changes to the water cycle. Sea levels are rising in some areas and dropping in others, glaciers are retreating and disappearing affecting rivers, droughts are happening more frequently in some regions and floods in other areas, coastlines are changing and some islands are disappearing, the polar ice cap is melting, and so forth.

B) A high literacy rate increases the standard of living.
Explanation:
The literacy rate shows how many people are able to read, write, and comprehend the written material. The literacy rate of the country depends a lot on the standard of living. Those who are not literate can’t peruse high education and find a well-paid job, so they are most likely to live in poverty.
It also prevents the country to have more people working jobs that better the living standard such as professors, doctors, economists, scientists, etc. These jobs are vital to the country's development. If people are not educated, they can’t add up to the growth of the country and its economy. Therefore, <u>the standard of life will be lower when there are more illiterate people, and higher when the literacy rate is high. </u>
