• If the direct speech is in the present simple, you change it to the past simple.
• If the direct speech is in the present continuous, you change it to the past continuous.
• If the direct speech is in the past simple, you change it to the past perfect.
• If the direct speech is in the present perfect, you change it to the past perfect as well.
• If the direct speech is in the past perfect, it stays the same.
• If the direct speech has can or will, you change it to could and would.

Answer: Never lie to anyone--it will only ruin your reputation.

Explanation:

Mark Twain in this excerpt is telling the youth not to lie because they would likely be caught and once caught, it would be very hard for people to completely trust them again because their reputation would be ruined.

Since t is the temperature of the water in the coffeepot, the required inequality expression will be t ≤ 210°
