Input: Consider Input: Context: Coming off their Sunday night road win over the Packers, the Cowboys went home for a Week 4 NFC East showdown with the Washington Redskins. In the first quarter, the 'Boys shot first as QB Tony Romo completed a 21-yard TD pass to TE Jason Witten. In the second quarter, the Redskins took the lead as QB Jason Campbell completed a 3-yard TD pass to WR James Thrash and a 2-yard TD pass to WR Antwaan Randle El, along with kicker Shaun Suisham getting a 20-yard field goal. Dallas closed out the half with kicker Nick Folk getting a 36-yard field goal. In the third quarter, the Cowboys tied the game with Romo completing a 10-yard TD pass to WR Terrell Owens. Washington would respond with Suisham kicking a 33-yard field goal. In the fourth quarter, the Redskins increased their lead with Suisham nailing a 33-yard and a 29-yard field goal. The 'Boys tried to rally as Romo completed an 11-yard TD pass to WR Miles Austin. However, Dallas' onside kick attempt failed, preserving the Redskins' win. 
 Question: Which player scored the last field goal of the game?

Output: shaun suisham


Input: Consider Input: Context: New software is able to analyze exactly how many hairs there are in a patch of skin and could help in testing the effectiveness of baldness treatments and depilatory creams, say Australian researchers. Researchers from CSIRO Mathematical and Information Sciences in prefix = st1 /Sydneyreport their findings in the November issue of the journalSkin Research and Technology. The software, developed with a UKcompany, will make it easier for researchers developing hair removal creams to accurately assess how well they work, says Dr Pascal Vallotton. "Up to now they were counting the number of hairs that survived after treatment by hand. That's hard work and it's difficult because you may count a hair twice or you may miss it." he said. The software relies on images captured by a small flatbed scanner pressed onto the skin. Using a mathematical algorithm , the software then identifies and traces each individual hair based on an understanding of a hair's unique features, such as its straightness. The software is able to distinguish between hairs and other features on the skin such as wounds or moles . "Our skin irregularities make it difficult to say this is a hair or this is a mole," Dr Vallotton said. Comparison between earlier and later images can also determine if hair is growing quickly or slowly, he says. Unfortunately, to check the accuracy of the software, the researchers still had to adopt the old-fashioned method of counting hairs, helped by volunteers from neighboring labs who put their skins on the line for science. "We had 12 volunteers, mostly from neighboring labs, and we acquired images of hair before and after treatment," Dr Vallotton said. To ensure an accurate count, the individual hairs had to be marked off as they were counted, but after such a laborious process, the researchers were pleased to discover the software results were comparable to the manual count. Dr Vallotton says the software could also be useful in testing the effectiveness of balding treatments and counting or tracing substances other than hairs, that are long and thin and otherwise difficult to image. 
 Question: What plays a key role in counting the number of hairs with the software?


Output: a scanner.
