So is it not ambiguous to write like this.
the way u wish to construct sentences wud be next to impossible !!
but I have a concern over "them" . It can refer to both
a) her books
b) her laptop + her books
and in case the sentence was her laptops and her books
"them" could have meant
c) laptops + books.
ask ur self does these 2 interpretations affect ur understanding of sentence !!
to me its all same !!
