Well I got my end of the summer party like I wanted . The few of us that were old enough went and got sake last night and whoa that stuff is beastly . Tony was just gone after like 1/2 an inche of it .

Question: Why do you supposed the author thinks that sake is Beastly ?
Answer: Most likely they got very drunk very fast from it ; they even state one of their friends was " gone " after drinking very little .Sake is beastly when you drink it at summer parties .None of the above choices .Because Tony was gone , meaning the beast ( the sake ) took him away .
