Critical Reasoning

A recent tracking survey has shown that the vast majority of users of Haplosoft's new text-editing software ignored the recommended tutorial that comes with the software. Some representatives of Haplosoft's marketing team expressed concern that the company would need to develop more attention-grabbing tutorial materials, or else users would fail to know how best to use the software. However, their concerns were assuaged when a Haplosoft engineer pointed out that ___________________.

A. most users look to the software to accomplish a limited range of tasks because that is all they know how to do.
B. the software packaging contains an instruction manual, which has most of the same content as the tutorial.
C. the tutorial is based on a rewritten version of specifications given to the marketing team by Haplosoft's engineers.
D. the tutorial contains information standard to most text-editing software and with which most users are already familiar.
E. historically, very few users have contacted Haplosoft's technical support line with questions about how to use the text editor.

OA : D

Need to help to understand why D is the right answer and NOT B. Option B explains another reason or cause which might cause people to not refer to the online tutorial. Doesn't Option D come with an additional assumption that the software is same as other standard text-editing software. In fact, the statement and concern of the marketing team suggests that there is a value(or reason) to read the manual.

B. the software packaging contains an instruction manual, which has most of the same content as the tutorial.

Instruction manual is out of scope. We cant even assume if people ever open the instruction manual or any thing about the manual.

D. the tutorial contains information standard to most text-editing software and with which most users are already familiar.

If the contents are already standard information with which most users are already familiar, no matter how much attention-grabbing tutorial materials is made the users would not be able to make the best use of the software.

A. most users look to the software to accomplish a limited range of tasks because that is all they know how to do. --> Does not relate to more attention grabbing tutorials
B. the software packaging contains an instruction manual, which has most of the same content as the tutorial. --> So what if the instruction manual is available, there could still be a need of a more grabbing tutorials
C. the tutorial is based on a rewritten version of specifications given to the marketing team by Haplosoft's engineers. --> Irrelevant
D. the tutorial contains information standard to most text-editing software and with which most users are already familiar. --> If users are already familiar with the contents of the manual, making the manual more attention grabbing is not going to help and hence this could be an answer.
E. historically, very few users have contacted Haplosoft's technical support line with questions about how to use the text editor. --> Does not relate to more attention grabbing tutorials

Based on above analysis, IMO OA is (D)
