I have a question about negating the cause, increased TV watching (~TV). I know this is a causal relationship question, but I was thinking about the contrapositive of ~TV. Could a contrapositive of ~TV be: 1.) People who did not increase their TV watching (their TV watching remained the same). 2.) A...

Hi blackbee! I'll provide an explanation. Anyone is welcome to correct me. :) Lets start off with this example, all As are Bs. From this we know that it must be true that most As are Bs. It also must be true that some As are Bs. Some relationships are reversible so we know that it also must be true ...

Hi everyone,

Could answer choice b be viewed as furthering the paradox because there is computer evidence that supports the accuracy of both reports?

That was a great explanation!! It cleared up my misunderstanding. I did not understand why PowerScore provided a numerical range for each formal logic word (all, none, most, some, most are not, some are not) but your examples made complete sense out of it all. I now understand how "some" c...

I think the answer to my question is a typical law school answer which is, "it depends". For example, in this statement, "Only a minority of those who engage in political action do so out of a sense of social justice", a "most are not" statement is accurate. The inheren...

Thank you again for the helpful response, Chike_Eze. I appreciate it! Your explanations make perfect sense. I know where my confusion came from. I was reviewing question 22 in preptest 42, section 4. I orginally diagrammed the first statement as a "some" statement but Manhattan diagrammed ...

Thank you for the quick response, Chike_eze! What you said makes perfect sense. I am still a bit confused though. I understand that A some B is equivalent to B some A, but I do not understand how A some B is equivalent to B some ~A? Any thoughts?

Hi everyone, I learned formal logic from the PoweScore Logical Reasoning book. PowerScore says that the "some" relationship is reversible. So, for example, A some-> B is reversible to B some-> A. I am reviewing a couple formal logic problems in my Manhattan Preptests 41-50 book and f...

Cool! Thank you very much!

I apologize for the silly question. I am new to Manhattan prep's terminology for RC. I purchased Mahattan's '10 Real Lsats Grouped By Questiom type', and I'm about to take the scale and pear practice in RC.

Thank you for your time.

I selected answer choice e.) thinking that if adults lost weight (fat) as they became older, that would explain why the percentage of fat in a person's diet stays the same (because they burned off excess fat they gained as a result of consuming more fat as they got older). I think one of the main re...

^That was one AWESOME explanation! Thank you, WaltGrace.

I have a random question. If this question was a sufficient assumption question instead of an inference question, would it be possible for answer choice C or E to be correct? The last sentence of the stim. could be viewed as the conclusion. The conclusion being that accidents due to human error and ...

I have come to the conclusion that I am retarded because I still do not understand why answer choice B is correct. Can someone provide a different explanation, please? This is my understanding; a comet's mass is based on how bright it is. So, if a comet's brightness is at a level of 10, for example,...

I reviewed this problem a couple of times and still arrived at the wrong answer. The first time I thought the answer was A. I reviewed this question for the first time months ago so I do not remember why I thought A was the correct answer. I reviewed this question today and narrowed down the correct...

Great explanations, but I have the same question as nemeshb. I am wondering how we are supposed to realize that the total amount of coal remaining carries over to the next year? The question is not as difficult when that piece of information is known, but was very difficult for me to grasp when I di...

Thank you for the response! Some of those answers really threw me for a loop! I thought that my understanding of conditional relationships was completely wrong after taking the quiz. I do not know if this matters or not, but I took the quiz using my phone. Maybe that has something to do with the err...

I selected the incorrect answer which is ~D -> G. I chose this answer because "only if" introduces a necessary condition and G followed the necessary condition indicator. So I thought that D could not be selected unless G, the necessary condition, was selected. This is what the wrong an...

Hi, I chose the incorrect answer which is D -> ~C. I thought that C and D must be forever apart so I chose the incorrect answer because the negation is on the necessary condition. I have been under the impression that when the negation is on the sufficient condition it is possible for both variab...

Thank you, OhthatPatrick! Your explanation is awesome and is extremely helpful. I understand now and learned something different too. I have been self-studying using the PowerScores books and even though they do a good job of classifying question types, they tend to lump different question types (su...
