Of the eight students -- George, Helen, Irving, Kyle, Lenore, Nina, Olivia, and Robert -- in a seminar, exactly six will give individual oral reports during three consecutive days -- Monday, Tuesday, and Wednesday. Exactly two reports will be given each day -- one in the morning and one in the afternoon -- according to the following conditions:Tuesday is the only day on which George can give a report.Neither Olivia nor Robert can give an afternoon report. If Nina gives a report, then on the next day Helen and Irving must both give reports, unless Nina's report is given on Wednesday.If Kyle and Lenore do not give reports, then the morning reports on Monday, Tuesday, and Wednesday, respectively, could be given by
Answer(s): D
The question asks for a possible roster of morning students given that Kyle and Lenore - our two floaters - are the 2rejected ones. All that's being tested is your command of Rule 2: Since our 2 rejected ones have been named, then Olivia and Robert must be chosen to report, and Rule 2 demands that their slots be mornings.

Answer(s): B
The rather intricate wording might suggest a good "skipper," since we may learn more about which pairs can or cannot share a day in subsequent questions. (At the very least, subsequent questions are likely to be simpler to read and understand than this one.) But in the end it doesn't prove too difficult. The word "Wednesday" might suggest Rule 3, and are reading of Rule 3 might suggest that if Nina is to share a day with either Helen or Irving, that day would have to be Wednesday. And sure enough, "Helen + Nina" is what LSAT chose as option [Helen and Nina]. "Irving + Nina" would also qualify. Rule 1 in and of itself makes option [George and Lenore] incorrect - George cannot report on Wednesday, period; and it's relatively easy to work out, if you need to, that Irving and Robert., or Kyle and Nina, or Olivia and Kyle could each share the Tuesday slots, not necessarily Wednesday's.

Answer(s): A
The if clause identifies three of the 6 chosen reporters, and leaves it to us to (1) figure out as much as we can for certain, and (2) decide which of the five choices could be true. George is reporting, so he must take a Tuesday slot (Rule 1). Now, we don't know whether it's am or pm, but we do know (again, the question stem) that Nina and Robert appear on different days from each other and from George. Moreover, Nina cannot occupy a Monday slot here (because of Rule 3; for Nina to report on Monday she'd have to be followed by Helen + Irving on Tuesday, which is impossible now). So! Nina must take a Wednesday slot, and Robert will report on Monday morning (Rule 2). There's a lot left open, but we have shown that options [Helen gives a report on Wednesday], [Nina gives a report on Monday] and [Robert gives a report on Wednesday] are impossible (Nina's on Wednesday and Robert on Monday); and since Olivia, like Robert, is restricted to the am (Rule 2), Option [Olivia gives a report on Monday] is impossible as well. Option [Helen gives a report on Wednesday] is left over and must be correct. Indeed, Helen can share Wednesday with Nina.

Exactly two reports will be given each day -- one in the morning and one in the afternoon -- according to the following conditions:Tuesday is the only day on which George can give a report.Neither Olivia nor Robert can give an afternoon report. If Nina gives a report, then on the next day Helen and Irving must both give reports, unless Nina's report is given on Wednesday.If Kyle gives the afternoon report on Tuesday, and Helen gives the afternoon report on Wednesday, which one of the following could be the list of the students who give the morning reports on Monday, Tuesday, and Wednesday, respectively?
The question is: Which of the five choices is a possible listing of the morning folks? First, we ought to skim for the obvious rule violators, and option [Nina, Irving, and Lenore] can therefore be quickly eliminated: Nina cannot take Monday here because we cannot have "Helen + Irving" on Tuesday (Rule 3). Next, work with the choices.

If Nina gives a report, then on the next day Helen and Irving must both give reports, unless Nina's report is given on Wednesday.If Helen, Kyle, and Lenore, not necessarily in that order, give the three morning reports, which one of the following must be true?
Did this question's "if" bring one fact immediately to the forefront? We hope so: If Helen, Kyle, and Lenore are the morning speakers, then irrespective of their speaking order, Olivia and Robert are left out. We saw when analyzing Rule 2that squeezing these two out of the morning means squeezing them out of the schedule altogether. So with Olivia and Robert out, and Helen, Kyle, and Lenore (order still undetermined) filling the am slots, who's left for the pm's? George, Irving, and Nina, of course, and here we can be certain. Rule 1 demands that George be on Tuesday; and Rule 3 demands that under these circumstances, Nina be on Wednesday. So Irving for sure will get the Monday afternoon slot, and that's option [Irving gives a report on Monday]. Of the wrong choices option [Irving gives a report on Wednesday] is impossible, the others possible only.
