Logic-Grid
Logic Grid puzzles come with a handy interactive grid that will help you solve the puzzle based on the given clues.Logic-Grid
Five college seniors---John, Oscar, Earl, Ernie, and Marvin---rent an off-campus house. Each one is majoring in a different subjet---psychology, chemistry, biology, math, or physics. They are attending college on sports scholarships in five sports: football, baseball, track, tennis, and swimming. And each is taking a different foreign language: French, Spanish, Italian, German, and Russian. From the clues given, try to determine the language, the sport, and the major of each of the five students.
1. The biology major, the swimmer, the student taking Italian, and Marvin have never missed any of Ernie's home football games.
2. Neither Oscar nor Earl is the one who takes Spanish or the one who is a physics major, but one of them is a baseball player.
3. Marvin and the track star had lunch with the math major and later met Oscar after his German class.
4. The baseball Player, the math major, and Oscar all have rooms on the top floor, whereas John and the physics major have rooms on the ground floor.
5. The psychology major is taking German.
6. The biology major is not the track star and does not take Russian.

I was unable to fiure out who took Spanish and who took Russian. Can someone help me out as to where those answers come in?
WOW, keep these coming
I'm with Dragonfly. I see no way to differentiate between Ernie and Marvin taking Spanish or Russian!
Other than that this is a good puzzle!

I mean I'm with Dragonfantasy
I had trouble with who took Russian and Spanish, too!
Finally figured it out in Clue #2. The person who takes Spanish the the Physics major are different people. I can't believe it took me so long to figure that out!!
Good teaser!

Good teaser!
Thanks, Optimist, can't believe I missed that, now it is so obvious. Good Job Teaserboy
Clue #2 does NOT preclude the physics major from taking Spanish!
This teaser can NOT be logically solved with only these clues. I enjoyed it anyway because it was otherwise cleverly worded.

Good Job Teaserboy - it took awhile and my guess was the right answer.
The puzzle is solvable with the clues given. I was also left with Russian and Spanish at the end, but when I reread #2 it made sense as I had already determined that the physics person did not take spanish. Good puzzle. Really makes you think!
2. Neither Oscar nor Earl is the one who takes Spanish or the one who is a physics major. Chaskey, the or between the one who takes Spanish and the one who is the physics major means that they cannot be the same person.
this teaser was really easy
I think clue number 2 can be interpreted different ways. It could be that the physics major and the person who takes spanish are mutually exclusive. However, it can also be read (the way I did initially, as did many of you) that even though neither friends majored in physics OR took spanish, it is possible that somebody COULD in fact major in physics AND take Spanish. The clue is confusing...you need to make an assumption. Other than that, I enjoyed the teaser.
I have a hard time making assumptions. However, that didn't take the fun out of the teaser.
Sorry, but Clue #2 is grammatically correct to logically declare they don't do Spanish OR physics. This entire grid is possible with logic only; no assumptions!
But... if he wanted to make it easier, he could change 2
FROM: ...is the one who takes Spanish or the one who is a physics major, but one of them is a baseball player.
TO: ...takes Spanish or majors in Physics, but one plays baseball.

Splatt, clue #2 is ambiguous. For example, I am not the one who said, "This entire grid is possible with logic only..." and not the one who said, "...no assumptions!" That does not necessarily mean that you, Splatt, are two people.
I am in agreement with chaskey it can not be done with pure logic,you have to make a guess or an assumption
I wonder how "monet601" could determine that the physic didn't do spanish before rereading clue 2 ??
I couldn't figure out what half the ppl did so I think you need to relook this puzzle.
I got stuck on the Spanish and Russian, too. Thanks to the person who pointed that out. Once I reread it, I think that it can be solved logically, I just didn't notice it
Haha, I ALSO got stuck on the Spanish and Russian , but I FINALLY figured it out. GREAT JOB ! Very fun!
FUN!! I like to work puzzles that have a lot of drama in their comment boxes. Keep them coming!!
I couldn't figure out the Spanish and Russian either.
So I finally just guessed. And I guessed wrong.
But after reading some comments, I understand how you can figure out the Spanish and Russian part.
Great teaser!!

I also got stuck on the same part -- but once I re-read #2, as previously stated, the logical answer was crystal clear. I blame this on my being half-asleep while doing the puzzle.
I really enjoyed this puzzle, but there have been several other puzzles (logic grid) which relied on the same wording used in clue #2 to be interpreted the opposite. They used that wording as a gotcha for people who made the assumption incorrectly. I agree that although the clue is gramatically correct, it does not logically add up to that some *other* person can't do both.
I don't see how clue 2 can determine that the one taking spanish and physics are 2 different people. The only way to come to that conclusion is to guess right or look at the answer assume clue 2 was refering to 4 different people. I agree with Dragonlove that the wording is intended as a gotcha.
The only way I see to get stuck on who took spanish and who took physics is to take clue to to be intended the way it reads. That Neither Oscar nor Earl is the one who took spanish or the one who took physics. To interpret that this clue is talking about 4 people makes it impossible which one of the 4 is the one who played baseball. Without figuring out who plays baseball you can't get half the other info to get stuck.
I enjoyed this teaser, but I am one of those that got stuck with spanish and physics. I now know that the intent of clue 2 was to state that the student taking spanish and the student majoring in physics are 2 different people, HOWEVER, it CAN be interpreted the other way. It is NOT mutually exclusive. The clue states that neither Oscar nor Earl take Spanich or Physics. It does not preclude the Physics major from taking Spanish.
Like everyone else I was stuck on who spoke Russian and who spoke Spanish. I figured it out once I read the comment section, which suggested reading clue 2 again. It definately was a thinker. Great job!
