In this task, you will be presented with a context passage, a question about that paragraph, and a possible answer to that question. The task is to check the validity of the answer. Answer with "Yes" or "No".

Q: Sometimes traits can vary from parent to offspring. These changes are due to mutations. Mutations are a random change. Mutations are natural. Some mutations are harmful. In this case, the organism may not live to reproduce. The trait will not be passed onto offspring. Others variations in traits have no effect on survival. Can some mutations be good for a living thing? Other mutations can have great benefits. Imagine being the first moth that can blend into its background. It would have a better chance of survival. A living thing that survives is likely to have offspring. If it does, it may pass the new trait on to its offspring. Thats good news for the offspring. The offspring may be more likely to survive. Mutations are one way living things adapt to new conditions. <sep>Is a moth that is able to blend into its background more likely to have offspring than if it cannot blend into its background?<sep>No

A: No

Q: Little is known of the earliest Stone Age inhabitants of Europe's southwestern extremity. The ancient Greeks called them the Cynetes (or Cunetes). Whatever their origins, their culture evolved under the pressure and influence of foreign forces. Among the many invading armies that settled here and contributed to nascent Portuguese culture were Phoenicians, who settled in the area around 1,000 b.c., followed by the Celts, Iberians, Greeks, and Carthaginians. But it was the Romans, who arrived late in the third century b.c., who most greatly influenced all of Iberia. They built towns, industries, roads, and bridges, developed agriculture, and bequeathed the Latin language, of which Portuguese is a direct descendant. The Romans named the southwestern province of the peninsula Lusitania, oddly enough for one of the Celtiberian tribes they defeated, and by the third century a.d. had introduced Christianity. By the beginning of the fourth century the Algarve had a bishop in place, based in Faro. But Rome had already fallen into decay, and soon hordes of northern tribesmen took over the empire. The Algarve fell to the Visigoths in the mid-fifth century. Under Moorish Rule In a.d. 711, the Moors brought powerful armies from North Africa and launched a devastating attack on the Iberian peninsula, conquering much of what would become Spain and Portugal. They imposed Islam and left an indelible influence on the countryside and the population of the Algarve. The Moorish legacy can still be seen in the form of wells and waterwheels, squat white houses, the dark complexions of the people, and in the very name given the regiontaken from Al-Gharb, which means "country of the west" (when the Moors conquered the territory, it was the most westerly in the known world). The Moors governed their Iberian kingdoms from across the border in Seville, but the Algarve had its own regional capital and huge, invulnerable fortress. The capital was Chelb (or Xelb), and it was bigger and better defended than Lisbon. Today the town, known as Silves, is a provincial outpost whose only besiegers are busloads of tourists who climb the narrow streets up to the old Moorish ramparts. <sep>What was the Portuguese city of Silves was once known as?<sep>The Cynetes (or Cunetes)

A: Yes

Q: As where to guard the walls, full many a foss Begirds some stately castle, sure defence Affording to the space within, so here Were model'd these; and as like fortresses E'en from their threshold to the brink without, Are flank'd with bridges; from the rock's low base Thus flinty paths advanc'd, that 'cross the moles And dikes, struck onward far as to the gulf, That in one bound collected cuts them off. Such was the place, wherein we found ourselves From Geryon's back dislodg'd. The bard to left Held on his way, and I behind him mov'd. On our right hand new misery I saw, New pains, new executioners of wrath, That swarming peopled the first chasm. Below Were naked sinners. Hitherward they came, Meeting our faces from the middle point, With us beyond but with a larger stride. E'en thus the Romans, when the year returns Of Jubilee, with better speed to rid The thronging multitudes, their means devise For such as pass the bridge; that on one side All front toward the castle, and approach Saint Peter's fane, on th' other towards the mount. <sep>Which way did the naked sinners come?<sep>From above

A:
No
