Hey, would some mind explaining this question for me. Not really understanding the last part of the explanation.
It's easier to understand the last part if you skim over the first bit again after reading it. Basically, your bag of letters was (referring to the 2nd paragraph) a bag of 80 letters with 0.4 x 80 = 32 vowels, more than (0.6 x 80)/2 = 24 which are either B, T, S, H, N, R or C, and just one of Z, X, J and Q. This information presented in the second paragraph is distracting and the first paragraph contains most of the necessary information.View attachment 3804

This works. There cannot be an animal which is both "not a bird" and "does have feathers". So an animal must be at least one of "a bird" or "does not have feathers". A featherless bird falls into both categories, which fulfills "or".Could someone please explain this to me. The irony of this statement is that UCAT gave the example of 'featherless birds' in their prior answer responses but didn't apply it to this one.
Am I simply missing something here, or have UCAT failed with their syllogism logic once again?
So the statement is "An animal is a bird or it does not have feathers". In the instance of a featherless bird, we have An animal which is a bird but does not have feathers - thus fulfilling the category of an animal that is a bird and does not have feathers. Thereby, complying with both sides of the statement - an animal that "is a bird" and it "does not have feathers". I still don't understand....This works.

It was established earlier in the thread that "or" can include "and". Basically, if you manage to colour in the whole Venn diagram with both possibilities, regardless of whether there is overlap, then it is true.So the statement is "An animal is a bird or it does not have feathers".

Do you have an example using this?It was established earlier in the thread that "or" can include "and". Basically, if you manage to colour in the whole Venn diagram with both possibilities, regardless of whether there is overlap, then it is true.
The only time you don't want any overlap is when the question specifically says "x is a or b but not both".
How do you know males even play golf? It never gives info on males at all. There could be zero males that play golf.How would everyone respond to this statement?
"All teachers at this school are male. No teacher at this school play golf"
"Some males play golf"
I would answer yes - as I think this comes back to what A1 mentioned prior. Along the lines of UCAT 'taking the benefit of the doubt' of the possibility that it could be yes considering the minority of males at this school in comparison with the large set of "all males". The wording of 'some' also implies a positive response (from me at least) tending towards a "Yes" than a "No".
Would be delighted to hear others' inputs on this!

I know. This is what I was wrestling with before in the thread. The UCAT response in their question banks follows this logic, however.How do you know males even play golf? It never gives info on males at all. There could be zero males that play golf.
The answer is no. You can't say some males play golf - the only sample of males given in the statement is the teachers at the school, where none of them play golf. There is no benefit of the doubt when the passage is clear-cut about it - benefit of the doubt applies more to qualifiers such as 'may' where the passage has supporting information.How would everyone respond to this statement?

The same could be argued for the example I just referenced - yet the answer is apparently "yes"The answer is no. You can't say some males play golf - the only sample of males given in the statement is the teachers at the school, where none of them play golf. There is no benefit of the doubt when the passage is clear-cut about it - benefit of the doubt applies more to qualifiers such as 'may' where the passage has supporting information.
All the tourists at the resort are Europeans, representing a subset of the overall population of Europeans that exist. None of the tourists at the resort like trekking. Therefore, some Europeans don't like trekking. Some = not all.I know. This is what I was wrestling with before in the thread. The UCAT response in their question banks follows this logic, however.
Look in this example at Statement Number 3. Then look at the response.
I think what OP is referring to is that in the European example, there is no information as to whether any Europeans like trekking at all, thus unable to fulfill with certainty the criteria "not all".All the tourists at the resort are Europeans, representing a subset of the overall population of Europeans that exist. None of the tourists at the resort like trekking. Therefore, some Europeans don't like trekking. Some = not all.
versus
All teachers at the school are male, representing a subset of the overall population of males. No teachers at the school play golf. We cannot assume that some males play golf, as there isn't any information in the passage to support this - assuming this would be extrapolating beyond the confines of the passage. Therefore, the answer here is no.
Hope that clears it up
Oh ok I think you meant 'all teachers at this school are male and all teachers play golf. 'Question is 'some males play golf.' In this case the answer is yes as although the subset of males: teachers all play golf, there could be a broader category of males who don't play golf, hence not 100% of males play golf.How would everyone respond to this statement?

I would answer yes - as I think this comes back to what A1 mentioned prior. Along the lines of UCAT 'taking the benefit of the doubt' of the possibility that it could be yes considering the minority of males at this school in comparison with the large set of "all males". Effectively, the sub-section of "males at this school" cannot be representative of the larger encompassing "males" in general. The wording of 'some' also implies a positive response (from me at least) tending towards a "Yes" than a "No".

hi, im from the uk - but i was wondering if anyone had any tips for the yes or no questions? I tend to get all of the others right but these i really do struggle
also is it better to do the others first, then the yes and no last? I'm not too sure about what order to do them in

Do keep in mind that they're worth two marks BECAUSE they're harder and more time-consuming, you're not exactly doubling your marks by doing them first. For me, some of the later questions in DM are basically free marks (probability, Venn diagrams and sometimes logic puzzles), so I used to do them first to make sure I'd taken care of all the low hanging fruit, then portion out my remaining time to the 2-mark syllogisms. peachesss experiment a bit to see what works best for you.i don't really have tips as i am not the best at it either ( but i heard that the yes no questions should be prioritised as they are worth 2 marks compared to the others that are worth 1
Ah yes, that clears it up, though It still seems unreasonable because all males could play golf, and given some≠all the conclusion couldn't be drawn. Regardless, I'll stick with their response demonstrated in their practice tests!Oh ok I think you meant 'all teachers at this school are male and all teachers play golf.
