Complete Question Explanation
(The complete setup for this game can be found here: https://forum.powerscore.com/lsat/viewtopic.php?t=33051)

The correct answer choice is (E).

If O hosts two meetings, then O must host a meeting in each semester:

• ____       ____
  
  _O_       _O_
  
  _M/V_ _M/V_
  Fall      Spring

With O being doubled, it is now the only city that can appear twice, and thus we know from the numerical distribution that M and V each can host only once (as is true for H and T as well). Thus, only two possible scenarios exist:


Scenario 1: M hosts in the fall, V hosts in the spring:

H and T are the two remaining cities that still must host, and when V hosts in the spring, T must host in the spring as well. H is then forced to host in the fall:

• _H_ _T_
  
  _O_ _O_
  
  _M_ _V_
  Fall Spring

Scenario 2: V hosts in the fall, M hosts in the spring:

H and T are the two remaining cities that still must host, and when M does not host in the fall, via the contrapositive of the first rule H cannot host in the fall and thus must host in the spring. T is then forced to host in the fall:

• _T_ _H_
  
  _O_ _O_
  
  _V_ _M_
  Fall Spring

Answer choice (A): Under scenario #2, H does not have to host a meeting in the fall, and thus this answer choice is incorrect.

Answer choice (B): Under scenario #1, T does not have to host a meeting in the fall, and thus this answer choice is incorrect.

Answer choice (C): Under scenario #1, M does not have to host a meeting in the spring, and thus this answer choice is incorrect.

Answer choice (D): In each scenario H and V do not host meetings in the same semester, and thus this answer choice is incorrect.

Answer choice (E): This is the correct answer choice. Both scenarios show T and V hosting meetings in the same semester.
