Before dusk set in , some of us started preparing the dinner . We had a hearty meal loaded with sinigang na baboy , grilled liempo , grilled hotdogs , and grilled eggplant . Before heading off to bed , some still went to swim while others continued their videoke marathon , and others started their booze escapade . And right before dawn , everyone finally got into their goodnight sleep . Day 2 .

Question: What may be the reason some went off to swim ?
Answer: They wanted to exercise before going to bed .None of the above choices .They wanted to throw up the food somewhere low key .They were too tired to move so decided to swim instead .
