Quizplus · Accepted Answer

Reading the table from line 136, we can choose four people by taking pairs of two-digit numbers. For example, the first pair of numbers is 32, so we could include person #32. The next pair is 46, so we include person #46. Continuing in this way, we can choose four people: 32, 46, 67, and 71. These correspond to choice B. The other choices either include numbers outside the range 20-99 or repeat numbers already selected.
