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

Input: Consider Input: Tanezumab is a humanized monoclonal antibody that specifically inhibits nerve growth factor as a treatment for chronic pain. This phase IIB study investigated the efficacy and safety of tanezumab for chronic low back pain vs placebo and naproxen. Patients (N=1347) received intravenous tanezumab (5, 10, or 20mg every 8weeks), naproxen (500mg twice daily), or placebo. The primary efficacy end point was mean change in daily average low back pain intensity (LBPI) from baseline to week 16. Secondary end points included mean change from baseline to week 16 in the Roland Morris Disability Questionnaire and Patient's Global Assessment (PGA) of low back pain. Tanezumab 10 and 20mg had similar efficacy profiles and significantly improved LBPI, Roland Morris Disability Questionnaire, and PGA scores vs both placebo and naproxen (P.05). Tanezumab 5mg provided improvement of PGA scores vs placebo (P.05), and naproxen resulted in significant improvement of LBPI vs placebo (P.05). Adverse event incidence was comparable across tanezumab doses but higher than with placebo or naproxen. Arthralgia, pain in extremity, headache, and paresthesia were the most commonly reported adverse events by tanezumab-treated patients. The most frequently reported adverse events resulting in discontinuation of tanezumab treatment were arthralgia and paresthesia; the highest frequency was observed with tanezumab 20mg (both 1.4%). Serious adverse event incidence was similar across treatments. In conclusion, tanezumab provided significantly greater improvement in pain, function, and global scores vs placebo and naproxen in patients with chronic low back pain.

Output: What is the target of tanezumab?

Input: Consider Input: The 49ers meet the Ravens for the first time since Super Bowl XLVII, in which the Ravens won 34-31. In the second quarter, Colin Kaepernick threw a 76-yard pass to ex-Raven Torrey Smith to lead San Francisco 13-3. In the fourth quarter, Kaepernick threw another touchdown, this time to Quinton Patton, for 11-yard pass to lead the 49ers 25-13. This was Patton's first NFL touchdown. With the win, the 49ers have avenged their Super Bowl loss and broke their 4-game losing streak, and they go to 2-4.

Output: Who threw the longest touchdown pass of the game?

Input: Consider Input: Antonio Gates caught three touchdowns from Rivers to lead the Chargers to a 30-21 win over the defending Super Bowl champion Seattle Seahawks. San Diego held a 42:15 to 17:45 advantage in time of possession under hot weather conditions. The official game-time temperature was 94F (34C), while readings at field level read closer to 115F (46C). The Chargers had six drives of eight plays or moreincluding possessions of 14, 12, and 10 playswhile the Seahawks had one eight-play drive. San Diego's first possession was a 14-play drive that led to a 50-yard field goal by Nick Novak, ending the Seahawks' 20-game streak without allowing a score on the opening possession. Following a 10-play field goal drive by the Chargers in the second quarter, linebacker Kavell Conner forced a fumble on the kickoff, which led to a six-play touchdown drive; the two drives combined to keep the Seahawks offense off the field for almost nine minutes. Gates' third touchdown came after he split two defenders and made a spectacular one-handed grab to give the Chargers a 27-14 lead late in the third quarter. Rivers was 28-of-37 for 284 yards. He had thrown 65 touchdowns to Gates, the most between a quarterback and tight end in NFL history. The Chargers were 10-for-17 on third-down conversions, while the Seahawks were 3-for-8.
Output: Which team had the most third-down conversions Chargers or Seahawks?
