Question

How many square meters does the crystal coral cover in the experimental sample (18 m²) in 2007?

a) 18 square meters
b) 36 square meters
c) 324 square meters
d) 180 square meters

Answer 1

Without additional context or growth rate information, assuming that the area of the crystal coral remains the same as the experimental sample size, the area covered would be 18 square meters.

Step-by-step explanation:

The question seems to be lacking information required to provide an exact answer about the area covered by crystal coral in the experimental sample. The options provided suggest that the area could be one of the listed values, but without a specific growth rate or additional data concerning changes from a base year to the year 2007, we can't determine how much the coral has grown. Given only the information that the experimental sample started at 18 m² without any additional context, we could only assume that the area remains the same, so the answer would be 18 square meters (option a).
