The conjugation of "tener" that best completes the sentence is:
- Mike <u>tiene verguenza</u> de cometer errores cuando habla español.
Explanation:
The sentence translates in English: Mike is ashamed to make mistakes when he speaks Spanish, the other options are: is right (<em>it isn't applied because would mean that is right by making mistakes, which is contradictory)</em>, wants (<em>it isn't applied because would mean that Mike wants to make mistakes, something out of place</em>) and be careful (<em>could be used if the sentence was written in this form: Mike is careful not to make mistakes when he speaks Spanish</em>).
