TASK DEFINITION: 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.
PROBLEM: Context: Methicillin-resistant Staphylococcus aureus (MRSA) is a common multidrug-resistant (MDR) pathogen. We herein discussed MRSA and its infections in Krasnoyarsk, Siberian Russia between 2007 and 2011. The incidence of MRSA in 3,662 subjects was 22.0% and 2.9% for healthcare- and community-associated MRSA (HA- and CA-MRSA), respectively. The 15-day mortality rates for MRSA hospital- and community-acquired pneumonia (HAP and CAP) were 6.5% and 50%, respectively. MRSA CAP cases included pediatric deaths; of the MRSA pneumonia episodes available, 27.3% were associated with bacteremia. Most cases of HA-MRSA examined exhibited ST239/spa3(t037)/SCCmecIII.1.1.2 (designated as ST239Kras), while all CA-MRSA cases examined were ST8/spa1(t008)/SCCmecIV.3.1.1(IVc) (designated as ST8Kras). ST239Kras and ST8Kras strongly expressed cytolytic peptide (phenol-soluble modulin , PSM; and -hemolysin, Hld) genes, similar to CA-MRSA. ST239Kras pneumonia may have been attributed to a unique set of multiple virulence factors (MVFs): toxic shock syndrome toxin-1 (TSST-1), elevated PSM/Hld expression, -hemolysin, the staphylococcal enterotoxin SEK/SEQ, the immune evasion factor SCIN/SAK, and collagen adhesin. Regarding ST8Kras, SEA was included in MVFs, some of which were common to ST239Kras. The ST239Kras (strain OC3) genome contained: a completely unique phage, Sa7-like (W), with no att repetition; S. aureus pathogenicity island SaPI2R, the first TSST-1 gene-positive (tst+) SaPI in the ST239 lineage; and a super copy of IS256 (22 copies/genome). ST239Kras carried the Brazilian SCCmecIII.1.1.2 and United Kingdom-type tst. ST239Kras and ST8Kras were MDR, with the same levofloxacin resistance mutations; small, but transmissible chloramphenicol resistance plasmids spread widely enough to not be ignored. These results suggest that novel MDR and MVF+ HA- and CA-MRSA (ST239Kras and ST8Kras) emerged in Siberian Russia (Krasnoyarsk) associated with fatal pneumonia, and also with ST239Kras, a new (Siberian Russian) clade of the ST239 lineage, which was created through stepwise evolution during its potential transmission route of Brazil-Europe-Russia/Krasnoyarsk, thereby selective advantages from unique MVFs and the MDR. 
 Question: What is MRSA?

SOLUTION: mrsa

PROBLEM: Context: Today, nearly 400 animals are listed as threatened or endangered animals in the United States. Many are at risk of becoming extinct or disappearing permanently. Unless efforts to save these vulnerable animals succeed, many of the country's greatest creatures will be lost forever. From the facts listed, guess which animals are endangered. Click on the picture to find out more about each of these animals in trouble. American Crocodile *American crocodiles are about 12 feet long. They live on land and in shallow water, swamps and marshes. *American crocodiles like to float in the water with only their eyes and noses above the water surface. *American crocodiles eat mostly small animals, which they grab with their strong jaws and sharp teeth. *American crocodiles lay eggs. They hide their eggs under twigs and leaves, or bury them in the sand. *Some crocodiles help their young hatch, and then carry them to the water in their mouth. Habitat Southern Florida, Mexico, Central and South American, Caribbean islands. Why It's Endangered Overhunted for its skin and habitat destruction. Peninsular Bighorn Sheep *Bighorn sheep can weigh as much as 280 pounds and stand about 3 feet tall. *They live in dry, desert mountain ranges, near rocky cliffs. *Bighorn sheep eat grass, twigs and leaves. *Male sheep are called rams and can be recognized by their huge, brown horns. The horns curl back over the ears, down,and up past the cheeks. *They live in herds or groups. The male sheep with the biggest horns are usually in charge. Male horns can weigh as much as 30 pounds. *Males will use their massive horns to fight. The fights can last as long as 24 hours. *Females are called ewes. They are smaller than rams and have shorter, smaller horns. Habitat Nevada and California to west Texas and south into Mexico. Why It's Endangered Loss of habitat, hunting illegally, drought and disease. 
 Question: Where can we find both American crocodiles and Bighorn sheep according to the passage?

SOLUTION: mexico.

PROBLEM: Context: In Week 8, the Bears donned their 1940s throwback uniforms against the Carolina Panthers, who had the worst record in the NFC. The Bears scored first on Matt Forte's 13-yard touchdown run, which would be countered by Justin Medlock's 34-yard field goal. The Panthers then took the lead on Louis Murphy's fumble recovery; Panthers quarterback Cam Newton ran with the ball, and lost the ball when Bears safety Major Wright tackled him at the 1-yard line. The ball rolled into the endzone, where Murphy recovered it. Medlock would then kick three more field goals, and by the fourth quarter, the Panthers led 19-7. The tide eventually turned when Panthers punter Brad Nortman shanked a 6-yard punt, and Jay Cutler hit Kellen Davis on a 12-yard touchdown pass with less than seven minutes left in the game. On the first play of the Panthers' next drive, Tim Jennings intercepted Newton and returned the pick 25 yards to regain the lead 20-19, after Cutler's two-point conversion passing attempt was intercepted. Medlock later kicked another field goal to reclaim the lead 22-20 with 2:27 left in the game. Cutler would lead the Bears downfield, and Gould kicked a 41-yard field goal as time expired to give Chicago the victory. The kick was Gould's tenth game-winning field goal, and the first since 2010. 
 Question: What happened on the last play of the game?

SOLUTION:
field goal
