For Test 1, the high score is 98 and the average is 83. For Test 2, the high score is 95 and the average is 85. For Test 3, the high score is only 89 and the average is 76, so it doesn't meet either condition. For Test 4, the high score is 99 and the average is 81. Finally, for Test 5, the high score is only 92 and the average is 79, so it doesn't meet either condition. Therefore, the only tests that meet one of the conditions are Test 1, Test 2, and Test 4, giving us choice B as the answer. For Test 1: the high score is 100 and the average is 87, which means the average is greater than 80 and the high score is greater than 97.
For Test 2: the high score is 95 and the average is 78, which means only the high score is not greater than 97 or the average not greater than 80.
For Test 3: the high score is 90 and the average is 75, which means only the high score is not greater than 97 or the average not greater than 80.
For Test 4: the high score is 98 and the average is 85, which means the average is greater than 80 and the high score is greater than 97.
For Test 5: the high score is 92 and the average is 83, which means only the high score is not greater than 97 or the average not greater than 80.
Therefore, the best choice is B, including Test 1, Test 2, and Test 4.
