Problem: Given the question: Please answer correctly the following question related to the paragraph below. Which piece of iron is less magnetized? Kelsey is bored in class, and sees a coil of wire with electricity running through it. There is a box of random pieces of iron on the teacher's desk so she goes and picks up two of them. Piece A she simply puts on her desk to use later, and Piece B she slowly passes through the coil of wire. Hint: Our knowledge of electromagnets developed from a series of observations. In 1820, Hans Oersted discovered that a current-carrying wire produced a magnetic field. Later in the same year, Andre-Marie Ampere discovered that a coil of wire acted like a permanent magnet and Francois Arago found that an iron bar could be magnetized by putting it inside of a coil of current-carrying wire. Finally, William Sturgeon found that leaving the iron bar inside the coil greatly increased the magnetic field.

The answer is:
Piece A

Problem: Given the question: Please answer correctly the following question related to the paragraph below. Which company would most likely enjoy tax benefits of debt, company A or company B? Bob is a financial analyst. He used to work for company A. Bob noticed that company A is mostly financed by debt. Recently, he changed job and now working as a financial analyst for another company, company B. Company B has completely different culture than company A. Company B is mostly financed by equity. Hint: The trade-off theory of capital structure is the idea that a company chooses how much debt finance and how much equity finance to use by balancing the costs and benefits. The classical version of the hypothesis goes back to Kraus and Litzenberger[1] who considered a balance between the dead-weight costs of bankruptcy and the tax saving benefits of debt. Often agency costs are also included in the balance. This theory is often set up as a competitor theory to the pecking order theory of capital structure. A review of the literature is provided by Frank and Goyal.[2] An important purpose of the theory is to explain the fact that corporations usually are financed partly with debt and partly with equity. It states that there is an advantage to financing with debt, the tax benefits of debt and there is a cost of financing with debt, the costs of financial distress including bankruptcy costs of debt and non-bankruptcy costs (e.g. staff leaving, suppliers demanding disadvantageous payment terms, bondholder/stockholder infighting, etc.). The marginal benefit of further increases in debt declines as debt increases, while the marginal cost increases, so that a firm that is optimizing its overall value will focus on this trade-off when choosing how much debt and equity to use for financing.

The answer is:
company A

Problem: Given the question: Please answer correctly the following question related to the paragraph below. Which friend learned less about the amount of trapped terrestrial radiation increasing? Two meteorologists were good friends and discussed diverse issues weekly. This week they will talk again. Tim read about the Greenhouse Effect while Norm read about the mini-Ice ages. Hint: Greenhouse Effect: The solar energy reaching the surface of the Earth is concentrated in short wavelengths, which can easily penetrate the greenhouse gases, such as carbon dioxide and methane. The Earth, however, is cooler than the sun and it radiates its heat in the form of energy in the far infrared range. These longer wavelengths are partially absorbed by the greenhouse gases and some of the solar heat is returned to Earth. At a certain temperature these processes are in equilibrium and the surface temperature of the Earth is stable. However, if more greenhouse gases are put in the atmosphere the amount of trapped terrestrial radiation increases, leading to an increase in global temperature.
