9 runners—Lea, May, Nora, Olga, Pat, Queta, Rhea, Sue, and Tia—are divided into 3 relay teams. The 3 fastest runners are placed on team 1, the 3 slowest runners on team 3, and the remaining 3 runners on team 2.
No two runners run at the same speed. May runs faster than Queta. Queta runs faster than both Olga and Lea. Lea runs faster than both Sue and Nora. Tia runs slower than Olga. Rhea runs slower than Tia. Rhea runs faster than Pat.
Select the runner who could be on team 2 but not on team 3, and select the runner who could be on any team.

Team 2 but not team 3 - Olga.
Any team - Lea.
1. May runs faster than Queta -> M>Q
2. Queta runs faster than both Olga and Lea. Q > O & L
3. Lea runs faster than both Sue and Nora. L > S & N
4. Tia runs slower than Olga. O > T
5. Rhea runs slower than Tia. T > R
6. Rhea runs faster than Pat. R > P.
From above statements, M and Q are two fastest, so they will be in team 1.
From 4,5 and 6, definitely there are 3 persons who are slower than O, so O will not be in team 3.
From above statements it can also be seen that L can be in any team.

Let the first letter of each of the runners' names be their respective speeds.
Then, from the problem statement we can write the following relations:
1) m>q>o>t>r>p
2) m>q>l>s
3) m>q>l>n
i) From relations 1, 2 and 3, we can clearly see of all runners Olga (with speed o) could be on Team 2 (but never team 3) since there are 3 runners slower than her.
ii) Also from relations 1,2 and 3 we can say that Lea (with speed l) could be on any team (i.e. Team 1, Team 2 or Team 3) depending on her speed relative to others. For example if l > o (Lea is on Team 1); if o > l > at least one among t, r, p (Lea is on Team 2); and if p>l (Lea is on Team 3)
