Passage I

A team of researchers constructed a greenhouse, consisting of 3 artificially lighted and heated sections, to be used to grow food during a long space voyage. The researchers found the weekly average light intensity, in arbitrary units, and the weekly average air temperature, in degrees Celsius (°C), in each section. The results for the first 6 weeks of their measurements are given in Table 1 (weekly average light intensity) and Table 2 (weekly average air temperature).

5. Suppose the efficiency of illumination is defined as the intensity of light absorbed by the plants divided by the intensity of light provided to the plants. Based on the data, would one be justified in concluding that the efficiency of illumination was higher in Section 1 than in the other sections ?

Answer and Explanation

Your Answer is

Correct Answer is D

Explanation

It has been shown in the question stem that to calculate the efficiency of illumination, you need to know the intensity of

light provided and intensity of light absorbed. However, observing all the data in the article, I found that the experiment did not provide data about light absorbed, so it cannot be calculated
