BigBook questions

Hello,

  1. (Page 72 in BigBook) - In the related reading text for the question below, it seems that the Earth being smaller was mentioned. However, Greg considered the second option to be external knowledge. Could you please clarify this for me?

  2. I am having difficulty understanding the context and options in the question below. Could you please provide a clear explanation of each?

3.I understand why “incentive” is the correct choice, and I was hesitating between “incentive” and “alternative.” But why isn’t “alternative” correct? (test10 - page 402)

Hello,

Could anyone assist me with these questions?

  1. Alternative” doesn’t fit here because it suggests a replacement for some existing approach to creating a safer workplace, but the sentence doesn’t mention any such approach that fines are supposed to replace. It presents fines as a possible method to improve safety. If you pick “alternative”, it begs the question, “what is the other (current) method?”

The sentence discusses how Darwin treated key biological concepts. It says that race wasn’t important in his theory, and even species wasn’t defined clearly.

“Require” works because Darwin’s method didn’t need the idea of race as a core concept.
“Convenience” works because even species was treated more as a useful label than a strict scientific definition.

So the sentence means:
Darwin’s method didn’t need race as a concept; even species was mostly a theoretical convenience.
