6. How does the author reveal that Rikki is not boastful or conceited about killing Nag and Nagaina?

The end of Rikki-Tikki-Tavi includes the following:

    `He saved our lives and Teddy's life,'' she said to her husband. ``Just

    think, he saved all our lives!''

    Rikki-tikki woke up with a jump, for all the mongooses are light sleepers.

    ``Oh, it's you,'' said he. ``What are you bothering for? All the cobras are

    dead; and if they weren't, I'm here.''

    Rikki-tikki had a right to be proud of himself; but he did not grow too

    proud. . .

This shows that even though Teddy's mother believes it was a heroic feat to kill Nag and Nagaina, he acts like it's no big deal. The last sentence literally says that he wasn't proud (a synonym of boastful or conceited) even though he had a right to be.

that is the way of a cheater and cheaters get nothing but bad grades and in trouble.

the legal limit for the drivers who can drive after consuming any amount of alcohol is 21 years.

explanation:

on november 1, 1996, a "zero tolerance law" was put into effect in the new york state.

according to this zero tolerance law, for people under the age of 21 years, it was illegal to purchase and possess alcohol or to drive after consuming any amount of it.

also, the alcohol involvement rate for the drivers under the age of 21 was roughly twice that of elderly drivers.
