Read these lines: "In a safe place Tom examined two large needles which were thrust into the lapels of his jacket, and had thread bound about them, one needle carried white thread and the other black. He said: She would never have noticed if it had not been for Sid. Sometimes she sews it with white, and sometimes she sews it with black." What can be inferred from the two needles?

1. He carries two needles, and the only difference between them is the colour of the thread. 2. His own words explain why, since his aunt uses white thread on some days and black on others. 3. Carrying both colours lets him restitch a collar whichever thread she used, so the discovery is not left to luck. 4. Coming prepared to hide the evidence is option B. 5. Option A would leave no reason to carry two colours at once. _Source: Mark Twain, The Adventures of Tom Sawyer (1876), public domain_
