PLEASE HELP QUICKLY! SERIOUS ANSWER PLEASE Suppose you are reading a scientific article and want to know what the author’s independent and dependent variables were. How you can learn this by looking at the graphs in the report?
QUESTION 1:
A. If the graphs are in the forms of x, y scatter graphs, then the independent variable will be graphed along the x-axis, and the dependent variable will be graphed along the y-axis.
B. It is only possible to determine the independent and dependent variables from a graph if they are labeled as the independent and dependent variable.
C. If the graphs are in the forms of x, y scatter graphs, then the independent variable will be graphed along the y-axis, and the dependent variable will be graphed along the x-axis.
D. It is not possible to determine the independent and dependent variables from a graph.

QUESTION 2:
What are the three factors that contribute to water scarcity?
A. El niño, hurricanes, and ocean drought.
B. Climate change, overuse of groundwater, and water pollution.
C. Hurricanes, overuse of groundwater, and water pollution.
D. Climate change, ocean droughts, and water pollution.
QUESTION 3:
Brenda is telling a classmate that we really don’t need to worry about droughts because the supply of water on Earth is constant. Explain to Brenda and her classmate why droughts are a real concern.

A. The Earth’s water supply is not constant. When a drought occurs, the water from one area is gone forever. It is difficult for the water to be replenished in an area after a drought occurs.
B. The Earth’s water supply is fixed, so once it leaves an area, it tends to not go back to that area. It is possible for an area with a drought to never have water return.
C. The Earth’s water supply is fixed, but water changes locations and states constantly, so the amount of water in any given reservoir is not fixed. It is possible for a reservoir of useable water to run so low in volume that it can’t supply the area around it with the amount that is needed.
D. The Earth’s water supply is fixed, so once it leaves an area, it tends to not go back to that area. The areas that experience droughts are only areas where people do not live. It is only a concern for the plants and animals.
