Alan, Becky, Chris, and Darla need to schedule a two-hour meeting on Saturday to finish a group project. Is there a two-hour time block on Saturday during which everyone is free to meet?
(1) On Saturday, Alan can meet any time between 10:00 a.m. and 3:00 p.m., while Darla can meet any time after 1:00 p.m.
(2) On Saturday, Becky and Chris can meet any time between noon and 4:00 p.m.

Gentle note to all experts and tutors: Please refrain from replying to this question until the Official Answer (OA) is revealed. Let students attempt to solve it first. You are all welcome to contribute posts after the OA is posted. Thank you all for your cooperation!We need to find if we can schedule a 2 hr window gap for a meeting amongst the free time slots available for Alan, Darla, Becky and Chris.
Statement 1:
(1) On Saturday, Alan can meet any time between 10:00 a.m. and 3:00 p.m., while Darla can meet any time after 1:00 p.m.
Alan free time is between 10:00 am and 3:00 pm.
Darla free time is after 1:00 pm.
over lapping time is 1:00 pm to 2:00 pm.
we don’t know the slots available for Becky and Chris.
Hence, Insufficient
Statement 2:
(2) On Saturday, Becky and Chris can meet any time between noon and 4:00 p.m.
Free slots for beck and Chris is 12:00 to 4:00 pm .
we don’t know the slots available for Alan and Darla.
Hence, Insufficient
Combining both statements.
We get the 2 hr time slot free for all is from 1 pm to 3 pm.
Hence, Option C.
