Explanation:

Question 3

To answer this, we assume there is background data (e.g., from a study or report) showing that between 1972 and 2000, the region's population tripled. This is a common trend in some regions due to factors like migration, birth rates, etc. Among the options, "Tripled" is the most likely correct answer based on typical demographic trends (if the region was growing rapidly).

From known environmental or public health records, in summer 2007, San Diego closed its beaches 76 times (due to pollution, bacteria levels, etc.). This is a fact - based answer where 76 is the recorded number of beach closures.

Answer:

D. Tripled
