Given a question and a context passage, generate the answer having the word or phrase from the context passage. Here, the answer should be a shortest continous span from the passage.

[EX Q]: Context: Hoping to rebound from their road loss to the Patriots, the Rams went home for a Week 9 NFC West duel with the Arizona Cardinals. In the first quarter, St. Louis struck first as QB Marc Bulger completed an 80-yard TD pass to WR Derek Stanley. In the second quarter, the Cardinals responded with a vengeance as safety Antrel Rolle returned an interception 40 yards for a touchdown, kicker Neil Rackers got a 36-yard field goal, RB Tim Hightower got a 30-yard TD run, and former Rams QB Kurt Warner completed a 56-yard TD pass to WR Jerheme Urban. In the third quarter, Arizona increased its lead as Warner completed a 7-yard TD pass to WR Anquan Boldin. In the fourth quarter, the Rams tried to come back as Bulger completed a 3-yard TD pass to WR Torry Holt (with a failed 2-point conversion). However, the Cardinals flew away as Rackers nailed a 30-yard field goal. During the game, the Rams inducted former Head Coach Dick Vermeil (who helped the franchise win Super Bowl XXXIV) onto the Rams Ring of Honor. 
 Question: Who caught a 3 yard touchdown pass?
[EX A]: torry holt

[EX Q]: Context: The human NEDD4 gene is located on chromosome 15q21.3, and consists of 30 exons that transcribe five protein variants of NEDD4, all of which vary in the C2 domain but share 100% identity from the first WW domain through to the end of the protein. 
 Question: What species is NEDD4 specific to?
[EX A]: human

[EX Q]: Context: Quantitative real-time PCR (QPCR) has emerged as an accurate and valuable tool in profiling gene expression levels. One of its many advantages is a lower detection limit compared to other methods of gene expression profiling while using smaller amounts of input for each assay. Automated qPCR setup has improved this field by allowing for greater reproducibility. Its convenient and rapid setup allows for high-throughput experiments, enabling the profiling of many different genes simultaneously in each experiment. This method along with internal plate controls also reduces experimental variables common to other techniques. We recently developed a qPCR assay for profiling of pre-microRNAs (pre-miRNAs) using a set of 186 primer pairs. MicroRNAs have emerged as a novel class of small, non-coding RNAs with the ability to regulate many mRNA targets at the post-transcriptional level. These small RNAs are first transcribed by RNA polymerase II as a primary miRNA (pri-miRNA) transcript, which is then cleaved into the precursor miRNA (pre-miRNA). Pre-miRNAs are exported to the cytoplasm where Dicer cleaves the hairpin loop to yield mature miRNAs. Increases in miRNA levels can be observed at both the precursor and mature miRNA levels and profiling of both of these forms can be useful. There are several commercially available assays for mature miRNAs; however, their high cost may deter researchers from this profiling technique. Here, we discuss a cost-effective, reliable, SYBR-based qPCR method of profiling pre-miRNAs. Changes in pre-miRNA levels often reflect mature miRNA changes and can be a useful indicator of mature miRNA expression. However, simultaneous profiling of both pre-miRNAs and mature miRNAs may be optimal as they can contribute nonredundant information and provide insight into microRNA processing. Furthermore, the technique described here can be expanded to encompass the profiling of other library sets for specific pathways or pathogens. 
 Question: Which polymerase transcribes pri-miRNAs?
[EX A]:
rnapii
