Question

what evidence from source 2 supports the idea that using a second language can be challenging?
the author mentions that they are proud of being fluent in spanish.
the authors father did not speak spanish and did not understand \lavadora.\
the authors brain needs to \actively choose spanish every time i say a word or construct a sentence,\ which can feel tiring.

Explanation:

The first option shows pride in fluency, not challenge. The second option is about the father's lack of knowledge, not the author's challenge. The third option directly mentions the mental effort and tired - ness in using a second language, which indicates a challenge.

Answer:

The author's brain needs to "actively choose Spanish every time I say a word or construct a sentence," which can feel tiring.
