Hi everyone,
I finished my June 2007 prep test and am now doing the blind review, however, I am still having trouble with figuring out questions 22 and 23 in the first section. The questions are regarding the recycling centres and materials. The rules for these questions are:
3 recycling centres (C1, C2, C3)5 materials (plastic, tin, glass, wood, newsprint)each centre recycles at least 2 but no more than 3 materialsany centre that recycles wood also recycles newsprint (WN)every material that C2 recycles is also recycled at C1Only one recycling centre recycles plastic, and that centre does not recycle glassQuestion 22 reads: "If Centre 3 recycles glass, then which of the following kinds of material must Centre 2 recycle?"
A. Glass
B. Newsprint
C. Plastic
D. Tin
E. Wood
Question 23: if C1 is the only recycling centre that recycles wood, then what could be a complete and accurate list of kinds of materials that one of the recycling centres recycles?
A. P, T
B. N, W
C. N, T
D. G, W
E. G, T
Would anyone be able to explain how to find the right answer for these questions?
Thank you in advance!
That helped so much, thank you!
