Do you think that reading multiple verses/chapters in Bible guarantee answer to prayers than single chapter? What is your take on this either as a Pastor, Rev.Father or experience Christian?

I have thought about this many times, as some Churches read longer chapters than others, I can't really say that prayers are granted base on the long reading of chapters.
I think in bothers on belief and purpose.
Just my opinion.

Looking at it in physically realm I think  just like any other thing we do, more we do a certain thing things the better, but I doubt if this will be the case in reading Bible. I think reading in the right direction would be the solution not length of chapters and verses.

I doubt if more chapters lead to any thing better, at least there is no where in the bible such is specified. I think what is said time without number is meditating in the word of God.

I think reading the bible always creates a question: should we look at the content critically or just as it is?

Bible always requires interpretation as people have been advised not to read bible as novel or ordinal books.
Reading bible I think needs critical think guided by knowledgeable persons. But it bothers on who is interpreting or guiding you about it as that is where the problem is. As anybody can interpret any verse to suit his/her life style. Of course judging by experience with religious leaders you're expected to take as it, as questioning things with logical thing will make them call you carnal person, thus leading to serious argument.
