Passage II

An experiment was conducted to determine how seawater temperature and salinity affect food consumption and growth in Scophthalmus maximus (a species of fish). The table shows, for each of 8 trials, average total food consumption, CT, and average gain in body mass for S. maximus kept at various temperature and salinity combinations. Each trial involved the same number of fish and lasted the same number of months.

Table adapted from Albert K. Imsland et al., "The Interaction of Temperature and Salinity on Growth and Food Conversion in Juvenile Turbot (Scophthalmus maximus)."@2001 by Elsevier Science B. V.

7. Based on the table, for which 2 trials was the average CT value less than 50 g and the average gain in body mass greater than 75 g?

Answer and Explanation

Your Answer is

Correct Answer is D

Explanation

Look at the last two columns corresponding to average Ct and average gain in body mass in the chart, and select the Trial with the first value less than 50g and the second value greater than 75g, which are 3 and 7 respectively, so option D is Normal answer.
