Input: Earths magnetic field helps protect Earth and its organisms. It protects us from harmful particles given off by the sun. Most of the particles are attracted to the north and south magnetic poles. This is where Earths magnetic field is strongest. This is also where relatively few organisms live. Another benefit of Earths magnetic field is its use for navigation. People use compasses to detect Earths magnetic north pole. Knowing this helps them tell direction. Many animals have natural 'compasses' that work just as well. Birds like the garden warbler in Figure 1.36 use Earths magnetic field. They use it to guide their annual migrations. Recent research suggests that warblers and other migrating birds have structures in their eyes. These structures let them see Earths magnetic field as a visual pattern.

Does the response "Sound echos off of objects" correctly answer the question "What do birds use to help in migration?"?

Input: Mr. Neville ( ( ( Anthony Higgins , a young and arrogant artist and something of a Byronic hero , is contracted to produce a series of 12 landscape drawings of an estate by Mrs. Virginia Herbert for her absent and estranged husband . Part of the contract is that Mrs. Herbert agrees '' to meet Mr. Neville in private and to comply with his requests concerning his pleasure with me . '' Several sexual encounters between them follow , each of them acted in such a way as to emphasise reluctance or distress on the part of Mrs Herbert and sexual aggression or insensitivity on the part of Mr Neville . Meanwhile , whilst living on the estate , Mr. Neville gains quite a reputation with its dwellers , especially with Mrs. Herbert's son-in-law , Mr. Talmann . Mrs. Herbert , wearied of meeting Mr. Neville for his pleasure , tries to terminate the contract before all of the drawings are completed and orders Mr. Neville to stop . But he refuses to void the contract and continues as before . Then Mrs. Herbert's married , but as yet childless , daughter , Mrs. Talmann , who has apparently become attracted to Mr. Neville , seems to blackmail him into making a second contract in Which he agrees to comply with what is described as her pleasure , rather than his a reversal of the position in regard to her mother . A number of curious objects appear in Neville's drawings , Which point ultimately to the murder of Mr. Herbert , whose body is discovered in the moat of the house . Mr. Neville completes his twelve drawings and leaves the house .

Does the response "A series of 12 landscaping drawings and the request for her to comply with his pleasures" correctly answer the question "What were the two parts of the contract that Mr. Neville had drew up for MRS. Virginia Herbert?"?

Input: 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.

Does the response "The organism with the harmful mutation may not live to reproduce, and thus the mutation will not be passed on to offspring" correctly answer the question "What might prevent a harmful mutation from being carried on into another generation?"?

Input: Reducing resource use means just what it says using fewer resources. There are lots of ways to reduce our use of resources. Buy durable goods. Choose items that are well made so they will last longer. Youll buy fewer items in the long run, so youll save money as well as resources. Thats a win-win! Repair rather than replace. Fix your bike rather than buying a new one. Sew on a button instead of buying a new shirt. Youll use fewer resources and save money. Buy only what you need. Dont buy a gallon of milk if you can only drink half of it before it spoils. Instead, buy a half gallon and drink all of it. You wont be wasting resources (or money!) Buy local. For example, buy local produce at a farmers market, like the one in Figure 2.20. A lot of resources are saved by not shipping goods long distances. Products bought at farmers markets use less packaging, too! About a third of what we throw out is packaging.

Does the response "Goods will not need to be shipped long distances" correctly answer the question "How does buying durable items save resources?"?
