I tried searching the forum before posting this but an error keeps occurring so I apologize if this has been discussed recently. Right now I am studying inference questions that deal with quantity statements. For the most part I understand what each particular word means (some, many, most, etc) but I am having trouble combining quantities that overlap to form an inference. I am going to provide you with a question from my study book that seems like a perfect example of a tricky quantity statement inference and I am hoping maybe some of you could help shed some light on how I should answer these questions.
In the Centerville Botanical Gardens, all tulip trees are older than any maples. A majority, but not all, of the garden's sycamores are older than any of its maples. All the garden's maples are older than any of its dogwoods.
If the statements above are true, which one of the following must also be true of trees in the Centerville Botanical Gardens?
A - Some dogwoods are as old as the youngest tulip trees
B - Some dogwoods are as old as the youngest sycamores
C - Some sycamores are not as old as the oldest dogwoods
D - Some tulip trees are not as old as the oldest sycamores
How I look at the question (quantity/group/characteristic):
All / TT / Older / M
Majority / S / Older / M
All / M / Older / D
Now, how do I determine which ones I can combine to form a new inference? When I combine two words what will they form? For example, some people like green and all people like shirts - does this then form "most people like green shirts?"
Any help would be appreciated and please feel free to ask me more questions if I have not explained my query well.
