4. is correct, but 10 is not.

The word you haven't used is "unquestioning" (f). So look up these words in the thesaurus: auspicious, implicit, unquestioning, promising.

What do you think?

so 4 will be 'i'

and 10 will be 'f' ?

Right.

To determine the correct answers for question #4 and #10, we can use the process of elimination and context clues.

1. adamant - unyielding
2. pathetic - pitiful
3. tangible - real
4. auspicious - This word implies something promising or favorable. "I" could be a possible answer, but let's examine the other options.
5. altruistic - unselfish
6. flippant - impudent
7. incorrigible - unmanageable
8. indolent - lazy
9. precarious - uncertain
10. implicit - This word suggests something unquestioning or implied. "I" seems like a possible answer, but let's consider the remaining options.

Based on the context and clues provided, the correct answers are:

4. auspicious - promising
10. implicit - unquestioning

Now let's update the list:

1. adamant - unyielding
2. pathetic - pitiful
3. tangible - real
4. auspicious - promising
5. altruistic - unselfish
6. flippant - impudent
7. incorrigible - unmanageable
8. indolent - lazy
9. precarious - uncertain
10. implicit - unquestioning

This way, each letter is used only once, and all the words are appropriately matched.
