It gives a comprehensive view on the information provided and may include instructions to do something, a report about new findings, or a description of something. Most often, it also requires the students to study and interpret dues, decipher them, and answer the question given. Example: Head the passage given be Low.
(1) The Sahara sets a standard for dry land, It's the worlds largest desert. Relative humrdrty can drop into the low single digits. There are places where it rains only about once a century. There are people who reach the end of their lives without ever seeing water come from the sky. Yet beneath the Sahara are vast aquifers of fresh warer, enough liquid to fill a small sea. it is fossil water, a treasure laid down in prehistoric times, some of it possibly a million years old. Just years ago, the Sahara was quite a different place, it was green. Prehistoric rock art in the Sahara shows something surprising: hippopotamuses, who need water year round.

At times when the Northern Hemisphere tilts sharply towards the sun and die planet makes its closest approach, the increased blast of sunlight during the North's summer months can cause the African monsoon fwhrch currently occurs between the Equator and roughly 17*N latitude,) to shift to the North as it did 10,000 years ago, inundating North Africa.
(3) Around 5,000 years ago, the monsoon shifted dramatically southward again.
