Input: Grim disappeared upstairs himself, and returned about ten minutes later in the uniform of a Shereefian officer--that is to say, of Emir Feisul's Syrian army. Nothing could be smarter, not anything better calculated to disguise a man. Disguise, as any actor or detective can tell you, is not so much a matter of make- up as suggestion. It is little mannerisms--unstudied habits that identify. The suggestion that you are some one else is the thing to strive for, not the concealment of who you really are. Grim's skin had been sun-tanned in the Arab campaign under Lawrence against the Turks. The Shereefian helmet is a compromise between the East and West, having a strip of cloth hanging down behind it as far as the shoulders and covering the ears on either side, to take the place of the Arab head-dress. The khaki uniform had just enough of Oriental touch about it to distinguish it from that of a British officer. No man inexperienced in disguise would dream of choosing it; for the simple reason that it would not seem to him disguise enough. Yet Grim now looked so exactly like somebody else that it was hard to believe he was the same man who had been in the room ten minutes before. His mimicry of the Syrian military walk--blended of pride and desire not to seem proud--was perfect. 

Does the response "He used the mannerisms of officers to mimic" correctly answer the question "What other disguise did Grim use to hide himself?"?

Input: Fossils give clues about major geological events. Fossils can also give clues about past climates. Fossils of ocean animals on the top of a mountain? Ocean animals have been found on the Earths tallest mountain. Its hard to believe, but it is true. These fossils were found at the top of Mt. Everest. Mt. Everest is the highest mountain on Earth. These fossils showed that this entire area was once at the bottom of a sea. It can only mean that Mt. Everest was uplifted. In fact, the entire Himalaya mountain range was raised. It was forced up from the collision of two continents. Fossils of plants are found in Antarctica. Now, Antarctica is almost completely covered with ice. Plants do not grow in Antarctica. According to fossils, they once did. This means that Antarctica was once much warmer than it is now. These fossils tell us about Antarcticas past climate. 

Does the response "Ocean animal fossils have been found on Mt Everest" correctly answer the question "What are clues that the highest mountain on earth was once covered by sea?"?

Input: Brad, Texas (CNN) -- Authorities were working on plans Friday for residents who were forced to flee a wildfire in northern Texas to return home, a day after firefighters made progress battling the blaze that destroyed dozens of homes. The blaze in Palo Pinto County scorched 6,200 acres by Thursday, according to the Texas Forest Service. The fire is burning near the resort of Possum Kingdom Lake, near the town of Brad, about 100 miles west of Dallas. "We feel much better about this fire today," as the blaze is now 50% contained, said John Nichols, a spokesman for the Forest Service. He said evacuations were lifted for some residents forced to evacuate the fire, which was driven by high temperatures and dry winds. The wildfire has destroyed 40 homes and nine RVs since it began Tuesday, the Forest Service said Thursday. Firefighters were receiving support from aerial tankers and helicopters. Authorities are mapping out plans to allow residents to return to their homes, said Palo Pinto County Sheriff Ira Mercer. Authorities also are trying to open the lake for the Labor Day holiday, he said. On Wednesday, evacuations were ordered in several communities on the north side of the lake after the fire charged over a ridge and approached a dam on the lake, CNN affiliate WFAA reported. The wildfire was moving so fast that the Forest Service pulled out of its command observation post, telling journalists and onlookers to get out of the way of the fire. "My house is right through here, though it may be gone," Tom Hardeston told WFAA as he watched the fire. Nearby ranchers battled to save their herds from the encroaching fire. "I'm just moving them from pasture to pasture," Cindi McCoy told WFAA, referring to her livestock. "As one pasture burns, I'm moving them back to that one and bring(ing) them back around." 

Does the response "nine RVs" correctly answer the question "What was destroyed by the September Texas wildfires?"?
