Logic Games General Question on Wording (Between/After) Forum

[TwinGuns21]

Can someone explain the reasoning behind the wording in the following problem (Prep Test 32, Section 3, Question 18)

If exactly two compositions are performed after F but before, O then R must be performed?

The first time I diagrammed it as follows F_ _ O when in reality it needed to be diagrammed as F _ O

And how would you diagram the wording of the following rule?

At least two compositions are performed either after F and before R, or after R and before F

Thanks for the help.

[Hey-O]

Are you sure it should be F_O and not F_ _ O?

I think that they way you had it first is right.

[TwinGuns21]

I think so because otherwise wouldn't it violate the rule that says, (At least two compositions are performed either after F and before R, or after R and before F)

If you have a worked out version I'd love to reference it. I'm going to try and rework the entire problem then come back and check the thread.

I don't have the test in front of me but if the rule is:

IF exactly two compositions are after F but before O, then R must be performed... then it should be as follows:

If the situation calls for, at any time, F _ _ O .... then SOMEWHERE R is going to be performed.

It's not saying it has to be F _ _ O or F _ O, just that R must be included if it's F _ _ O.

AND THE CONTRAPOSITIVE:

IF there is NO R performed, then two songs can't follow F and be followed by O. In other words, if there is NO R (ie R MUST BE EXCLUDED for some reason), then F _ _ O is NOT POSSIBLE.

If someone can go to the practice test and help me out, I will be very grateful. I am truly confused on this question.

I diagrammed it as follows

O/ _ _ _ O/ _ _ L/H
S P

TF or RT

[/FR/] [/RF/] either combination cannot be

at least F_R or R_F

P>S

[/OS/] [/SO/] either combination cannot be

Using this information

the first question we are able to knock out b, c, and d

however a and e cannot be knocked out.

the only way e can be knocked out is if the correct diagram is [at least] F _ _R or R _ _ F

according to the wording in the setup, it should be F_R or R_F right?

I don't have the test in front of me but if the rule is

It's impossible to answer the question with his info, It actually say what position will R be in. R must always be used anyways.

To answer you question do a hypo:


_ F _ _ O _ _ _

Because O must be first or 5th and since it comes after F in this hypo its here.

_ F _ _ O _ _ L/H


L or H have to be 8th

_ F S _ O _ _ L/H

or

_ F _ _ O _ S L/H


Because there has to be one in between O and S


P F S _ O _ _ L/H

Because P must come before S, so in this instance T must be immediately after R

P F S L/H O R T L/H

Or, going with the other positioning of S

_ F _ _ O R S L/H

R must be sixth because there has to be at least two spaces between F and R

The correct diagram for question 18, as has been pointed out already, contains a block of [F _ _ O]. Exactly 2 after F and before O.

To answer your second question:
[F _ ... _ R] OR [R _ ... _ F]

That's if you must diagram it. And it's just the way I would do it; I have no idea if it's how any of the prep companies would do it. Personally, I'd just write:
2+ between F and R, either order

Same thing with the last rule:
[S _ ... O] OR [O _ ... S]
or
1+ between S and O, either order
