Essay

Identify for which claims, if any, support has been given in the following passage; and state in your own words the reasons that have been offered for these claims.
"The evening's 'official' party, thrown by the Samuel Goldwyn Co. to celebrate the premiere of its film Golden Gate, was noisy and crowded and located in one of the area's poshest ski lodges. But as usual, the serious action didn't begin until later, at the unofficial afterparties. The hot ticket that night at the Sundance Film Festival in Park City, Utah (pop. 4,468), was a bash thrown in a rented condo by the William Morris talent agency and 20th Century Fox. Actually, invitations were hardly needed; anybody who could find a parking spot on the clogged, snow-packed streets and squeeze through the crowd spilling out of the jammed condo could venture into the belly of the Hollywood beast."
