can you please explain why b and c are not the answer
i hope you will help me
thanks
Hello,
honey1. I would be happy to help out. If you think (B) is an irrefutable
statement because it perfectly parallels the second line of the passage, then you are correct. Choice (C), meanwhile, takes that same line and cobbles it together with the last line, such that companies involved in those activities from the second line now create, add, and contribute in certain ways. How to choose between the two? The good news is that neither one is the answer to the question being asked, which has us identify
the conclusion instead. We can identify that conclusion by an indirect process by paying attention to the transition
after all. This transition indicates that a reason, formally called a
premise, or multiple premises, will follow. If we have premises after the transition, then what precedes it must be the conclusion itself. Consider the following example:
a) It is highly unlikely that humans, of their own efforts, will make direct contact with intelligent, intergalactic alien life forms. After all, the nearest galaxy to the Milky Way is approximately 25,000 light years away, and the resources required to sustain human life aboard even the most technologically advanced human-made spacecraft would be far too great.
Notice that there are two premises—distance and resources—just as there are in the passage we are examining. If you were to remove the transition and reposition the first sentence so that it followed what is now the second sentence, you would create a perfect premise-conclusion argument. This is exactly how we can reinterpret the passage at hand:

After all, The design, production, testing, and marketing of new technology has itself become a growing industry that is turning around the fortunes of once-ailing communities. The companies involved create jobs, add to the tax base, and contribute to an upbeat spirit of renewal. [Therefore], technology is radically improving the quality of life in some communities, and not only by direct application of innovations.
Choice (A) is exactly what we want, and the transition, as discussed above, offers us the tell-tale sign we need to feel sure of our answer.

I hope that helps. If you have further questions, feel free to ask. Good luck with your studies.
