Question

which of the following is a reason why the demand for salt was as high as gold at one time?
a. salt could be used as medicine.
b. salt was necessary to preserve meat.
c. mansa musa gave away so much gold that salt was more rare than gold.
d. people did not know that items could be made out of gold.

Explanation:

In historical contexts, salt was crucial for preserving meat (and other foods) before refrigeration, making it highly valuable. Option A's use as medicine was less a primary driver of its high demand comparable to gold. Option C misrepresents the relationship (salt's value wasn't due to Mansa Musa's gold giveaway). Option D is incorrect as gold's use in making items was known, and this isn't related to salt's demand.

Answer:

B. Salt was necessary to preserve meat.
