Question 3

What conclusion did scientists likely draw from this study?

Accepted Answer

A) Rainy conditions may not be enough to dilute road salts that have high salt concentrations. Therefore, salamander clutches will experience minimal physiological damage. 
B) Rainy conditions are enough to completely dilute road salts that have high salt concentrations. Therefore, salamander clutches will not experience any permanent physiological damage. 
C) Rainy conditions are enough to completely dilute road salts that have high salt concentrations. Therefore, salamander clutches will experience minimal physiological damage. 
D) Rainy conditions may not be enough to dilute road salts that have high salt concentrations. Therefore, salamander clutches will face irreversible physiological damage.
