As a non native english speaker, I can clearly understand the first sentence "A strong tremor in her hand makes it impossible for her to use American Sign Language". Even if we do not know the meaning of tremor (this french word is not used since long), we can easiliy guess that it is an illness in the hands and not lose much from the understanding of the sentence. For the second sentence, I have to think a lot more to understand the structure of the sentence and to remove the ambiguities. After reading the second sentence, I am far less confident in my understanding than afer reading the first one.
