Given a context passage, generate a question from the passage such that its answer is shortest continous span from the passage.

Ex Input:
Hoping to rebound from their three-game losing streak, the Raiders flew to Dolphin Stadium for a Week 11 duel with the Miami Dolphins. In the first quarter, Oakland trailed early as Dolphins WR Ted Ginn, Jr. got a 40-yard TD run. In the second quarter, the Raiders responded with kicker Sebastian Janikowski getting a 21-yard field goal. In the third quarter, Oakland started to catch up as DE Jay Richardson sacked QB Chad Pennington in his own endzone for a safety. Miami would answer with RB Patrick Cobbs getting a 10-yard TD run. In the fourth quarter, the Raiders took the lead as Janikowski got a 37-yard field goal, along with WR Johnnie Lee Higgins returning a punt 93 yards for a touchdown. However, the Dolphins sealed Oakland's fate as kicker Dan Carpenter nailed a 38-yard field goal.

Ex Output:
Which player scored a safety?


Ex Input:
A common challenge in pathogen discovery by deep sequencing approaches is to recognize viral or subviral pathogens in samples of diseased tissue that share no significant homology with a known pathogen. Here we report a homology-independent approach for discovering viroids, a distinct class of free circular RNA subviral pathogens that encode no protein and are known to infect plants only. Our approach involves analyzing the sequences of the total small RNAs of the infected plants obtained by deep sequencing with a unique computational algorithm, progressive filtering of overlapping small RNAs (PFOR). Viroid infection triggers production of viroid-derived overlapping siRNAs that cover the entire genome with high densities. PFOR retains viroid-specific siRNAs for genome assembly by progressively eliminating nonoverlapping small RNAs and those that overlap but cannot be assembled into a direct repeat RNA, which is synthesized from circular or multimeric repeated-sequence templates during viroid replication. We show that viroids from the two known families are readily identified and their full-length sequences assembled by PFOR from small RNAs sequenced from infected plants. PFOR analysis of a grapevine library further identified a viroid-like circular RNA 375 nt long that shared no significant sequence homology with known molecules and encoded active hammerhead ribozymes in RNAs of both plus and minus polarities, which presumably self-cleave to release monomer from multimeric replicative intermediates. A potential application of the homology-independent approach for viroid discovery in plant and animal species where RNA replication triggers the biogenesis of siRNAs is discussed.

Ex Output:
Which are the smallest known subviral pathogens of plants?
