[EX Q]: Context: Hoping to rebound from a tough loss to the Patriots, the Bills would play their Week 2 home opener in an interconference duel with the Tampa Bay Buccaneers. This would be the first time that Buffalo ever hosted Tampa Bay in a regular season game, having played a preseason game with each other in 1977. In the first quarter, the Bills came out firing as quarterback Trent Edwards completed a 32-yard touchdown pass to wide receiver Lee Evans, safety Donte Whitner returning an interception 76 yards for a touchdown and kicker Rian Lindell making a 31-yard field goal. The Buccaneers would get on the board in the second quarter as quarterback Byron Leftwich completed a 42-yard touchdown pass to tight end Kellen Winslow, while Buffalo replied with Lindell getting a 43-yard field goal. Tampa Bay would close out the half as Leftwich completed an 8-yard touchdown pass to running back Carnell "Cadillac" Williams. After a scoreless third quarter, the Bills began to pull away as Lindell got a 43-yard field goal and Edwards completed a 43-yard touchdown pass to wide receiver Terrell Owens. The Buccaneers tried to rally as Leftwich completed a 6-yard touchdown pass to tight end Jerramy Stevens (with a failed two-point conversion), yet Buffalo closed out the game with Lindell nailing a 20-yard field goal. With the win, the Bills improved to 1-1. 
 Question: Who threw the fifth longest touchdown pass?
[EX A]: leftwich

[EX Q]: Context: The enzyme telomerase is activated in 80-90% of all human malignancies and immortal cell lines, where it functions to maintain the integrity of chromosomal-end structures called telomeres. Telomerase enzyme activity can be detected in whole cell lysates by a polymerase chain reaction (PCR)-based method referred to as the telomeric repeat amplification protocol (TRAP). The TRAP assay involves extension of an oligonucleotide through telomerase-mediated enzymatic addition of telomeric DNA repeats and subsequent PCR amplification of the extension products. While the TRAP assay as originally developed utilizes radioactively labelled nucleotides, protocols are provided herein for nonradioactive versions of the TRAP assay, with options for either qualitative assessment of TRAP products by polyacrylamide gel electrophoresis (standard TRAP), or quantitative analysis by real-time PCR (Q-TRAP). The Q-TRAP method poses the additional advantages of exquisite sensitivity, rapidity, and potential for adoption to a high-throughput format. 
 Question: What is the aim of the TRAP assay?
