Which of the following is not a risk factor for water intoxication?
a. a low body mass
b. heat stress
c. resting
d. overexertion
ocean and freshwater contamination
a. does not affect marine life
b. is not affected by agriculture
c. results from industrial activity
d. is independent of human activity

It is possible to be intoxicated by water, and some of the factors are definitely low body mass, heat stress, and overexertion. One-year-olds can be more prone to water intoxication than an adult (simply because adults have more cells to retain the water than a one-year-old), heat stress and hot weather can drive someone to drink a lot more water than they need, same with someone doing some kind of heavy physical exertion such as marathon running. As with resting, it is very difficult to get intoxicated with water unless you want to be intoxicated with water. so Resting wouldn't be a factor.

Ocean and Water contamination is caused by industrial activity, such as factories and farms since things like pesticides and chemicals can leak into fresh and salt water. You can bet that water contamination directly affects marine life and that it does have an effect on agriculture and is dependent on human activity.
