Hi everyone! I have a question regarding necessary assumption questions. I am trying to get a better understanding of NA questions, since this is the area I am struggling with. I seem to be going for answers that seem relevant and may strengthen the argument, but are not needed/required.
For example, let's use this example from lsat trainer,
Argument: "Because we locked the door, no one can break into our house."
A possible correct answer choice may look like: "One cannot break into the house going through the chimney."
Wrong answer: "The door is the only way in and out of the house, and the locked door is impenetrable."
Here is a second example:
Argument: "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."
A possible correct answer choice: "She does not get an excess of caffeine from drinking tea."
Wrong answer choice: "Coffee is the only substance she consumes that contains caffeine."
The problem that I am having with these two examples from lsat trainer is that I am not seeing how the wrong answer is wrong. I understand for NA questions we are looking for an answer choice that is needed in order for the argument to be true. I did the negation test for the wrong answer choices and they still seem correct. For example in the second argument, the wrong answer choice is "coffee is the only substance she consumes that contains coffee" and in my mind when I did the negation test it was "it is not the case that coffee is the only substance she consumes that contains caffeine" or "coffee is not the only substance she consumes that contains caffeine." If that is true, couldn't this be an answer that is required for the argument?? If coffee is not the only substance she consumes that contains caffeine couldn't this wreck the argument??
Any help is appreciated! Thanks everyone!
