Which theme does leo tolstoy explore in this excerpt

Read each of the following statements and place a checkmark next to each true statement: test-makers give away answers to questions in other questions. a test-taker should check every 20 answers or so to make sure the questions and answers match. long passages on tests should be read quickly to save time. words like best, least, and worst require the test-taker to make judgments about the correct answer. test-takers should not try to answer the questions in their minds before reading over the answer choices. test-makers use the same letter three or four times in a row to trick test-takers.
