It wasn’t a specific question with an A-E or match answer, but an example with some categorized possible assumptions on page 271.
My husband says I consume too much caffeine, but that is false. I only drink one cup of coffee a day, and one cup of coffee is not too much caffeine for a person to consume daily…
I am getting confused, as, in my mind, the ‘Required and Important’ assumption is the same as the ‘Fills the gap but is not required’ say the same thing. One is just stronger. In this case, I’m not sure why the statement is not both required and sufficient.
‘Required and important’ She does not get her excess of caffeine through other means.
Fills the gap but not required’ Coffee is the only substance she consumes that contains caffeine.
Essentially, it seems that both are saying that she does not get caffeine from other sources, and their negations would both say the same thing as well. The only differences I see are that one states excess where the other does not and one refers to substance and consumption. I suppose it’s primarily the two examples on 271. I understand the difference between necessary and sufficient statements, but the fills the gap options for the coffee example [and the one next to it on house locks] seem to fulfill the role of both.
