なら and から what's the relation?


> A：この本を読んでみてください。
>
> B：これ **なら** 難しくない **から** 、私にも読めそうです。

Google translator said "This is not difficult, so I can read it."  
It's somehow convincing translation but I don't yet get the meaning of なら and
から here in this sentence.




なら and から are not related. It seems that some intermediate grammars were used
to construct that sentence.

なら is a conditional=if (1 out 4 of them). It is used on a given context. It
means "if given that ... Then ..." In which the context is taken from the
conversations. A here told B to try reading the book.

これなら means "If given that it's this book then...". The book is already implied
so it's not being stated again. AならB => if given that A then B.

から connects two sentences with the preceding sentence is the reason and the
sentence after it is the result. To say, it means "because". AからB => Because
of A, B happens.

難しくないから、私にも読めそうです means "Because it(the book) is not difficult, it seems that
even I can read it"

Combined it means "Given that It's this book and it's not difficult, it seems
that even I can read it."
