Answer: lacking strength
Explanation:
The highlighted word is ''frail''.
The definition of frail in relation to a human being is someone who is physically weak and fragile.
In this context therefore, it is logical to assume that the word means that the person being referred to (the mother) is lacking strength. This would make sense because the mother is getting old and people get weaker as they age.
If you mean “is the statement correct?” kinda thing, then i believe you can’t speak french. you may be able to speak a little bit of french, but i don’t think you’ll be able to speak french fluently.
It looks good.
You did a nice job being descriptive and your grammar looks fine.
