Question

to collect salt this way, ocean water is channeled into large, shallow ponds called \salt pans.\ sunlight causes the water to evaporate, leaving salt behind. what can you conclude from this information?
a salt is always harvested in large quantities
b salt can be harvested from any water source
c salt dissolves in water but it does not evaporate
d salt will evaporate if it is left in the sun long enough

Explanation:

• Option A: The text only mentions using salt pans, not that salt is "always" harvested in large quantities. There's no indication of always.
• Option B: The text specifically mentions ocean water, not "any" water source. So this is incorrect.
• Option C: Since sunlight causes water to evaporate leaving salt behind, it implies salt dissolves in water (as it's in ocean water initially) and doesn't evaporate (as it's left behind). This is correct based on the information.
• Option D: The text shows salt is left behind when water evaporates, so salt does not evaporate. This is wrong.

Answer:

C. Salt dissolves in water but it does not evaporate
