Read the excerpt from an article published by the Centers for Disease Control and Prevention. Drinking water can prevent dehydration, a condition that can cause unclear thinking, result in mood change, cause your body to overheat . . . and kidney stones.
Answer
A
I read in a medical book that kidney stones can be very painful for a person.
B
I have tried to drink more water, but I just prefer something with some flavor.
C
Yesterday when I was at the train station, I saw them installing stations for refilling water bottles.
D
The other day, I did not drink much water, and I struggled to focus on my math homework.
Explanation
The excerpt says dehydration can cause unclear thinking. Choice D describes drinking little water and then struggling to focus, which connects directly to that effect. Choice A mentions kidney stones, but it only states that they can be painful rather than connecting them to dehydration.
