“How has the Indus River Valley changed from ancient times to today?”

The Indus River helped with irrigation and farming making the basis of human civilization.

Growing crops near the river allowed for irrigation giving more time for people to do other things creating jobs and helping the foundation of civilization as we know it.

b. after i get up in the morning,

explanation:

after is a subordinating conjunction that introduces a time clause. time clauses are dependent clauses used to indicate when something happened.

the clause "after i get up in the morning" tells when the action in the main clause (drinking a cup of coffee) happens:

"after i get up in the morning, i drink a cup of coffee." it is the most logical choice of all.
