example 15

If some means at least one or possibly all, can we not conclude that all genetic mutations in bacteria occur at random? Thus, allowing us to conclude that answer C also works?

Hi Kenken, thanks for the question.

Unfortunately, when clicking "view" I am unable to see the question you are referring to.

However, based on the key words used in your question. I think the question starts with "In experiments in which certain kinds of bacteria were placed in a generous supply of nutrients..."

Strengthen with sufficient premise.

If this isn't the correct question, please just let me know in the reply and we will be sure to address the relevant question!

C wouldn't be correct because it is giving us the condition that

"If all genetic mutations in bacteria are random, then all genetic mutations in every other life form are random also"

However, it is unsupported that all genetic mutations in bacteria are random. The passage says that the mutations that occurred specifically in these populations were random. Because of this, adding this additional premise does not strengthen sufficiently.

I hope this helps. Again, if it's the wrong question just let us know!
