Elettra stuck the little slip of paper, on which the recipe was written, into her shabby pocket-book without looking at it. She could read and write fairly well, and had been used to helping her husband the under-steward with his accounts at Muro, but even if she had looked at the recipe she would have understood nothing of the doctor's hieroglyphics and abbreviated Latin words. The prescription was for a preparation of arsenic, which Matilde had formerly taken for some time. The chemist would not make any difficulty about preparing twenty doses of it for the Countess Macomer, though the whole quantity of arsenic contained in so many would probably be sufficient to kill one not accustomed to the medicine, if taken all at once. But though Matilde was so anxious to have the stuff before luncheon, she had a number of doses of it put away in a drawer, which she took out and counted, after Elettra had gone. She opened one of the little folded papers and looked at the fine white powder it contained, took a little on the end of her finger and tasted it. Then, from the same drawer, she took a package done up in coarser paper, and opened it likewise, looked at it, smelt it, and touched it with the tip of her tongue very cautiously indeed. It was white, too, but coarser than the medicine. She was very careful in tasting it, and she immediately rinsed her mouth with water, before she tied up the package again, shut the drawer, and put the key into her pocket.

Question: "Who opened one of the little folded papers?"

OPTIONS:
- no
- yes

Answer: "Countess Macomer"

Response: no

Electronic theft by foreign and industrial spies and disgruntled employees is costing U.S. companies billions and eroding their international competitive advantage. That was the message delivered by government and private security experts at an all-day conference on corporate electronic espionage. "Hostile and even friendly nations routinely steal information from U.S. companies and share it with their own companies," said Noel D. Matchett, a former staffer at the federal National Security Agency and now president of Information Security Inc., Silver Spring, Md. It "may well be" that theft of business data is "as serious a strategic threat to national security" as it is a threat to the survival of victimized U.S. firms, said Michelle Van Cleave, the White House's assistant director for National Security Affairs. The conference was jointly sponsored by the New York Institute of Technology School of Management and the Armed Forces Communications and Electronics Association, a joint industry-government trade group. Any secret can be pirated, the experts said, if it is transmitted over the air. Even rank amateurs can do it if they spend a few thousand dollars for a commercially available microwave receiver with amplifier and a VCR recorder. They need only position themselves near a company's satellite dish and wait. "You can have a dozen competitors stealing your secrets at the same time," Mr. Matchett said, adding : "It's a pretty good bet they won't get caught." The only way to catch an electronic thief, he said, is to set him up with erroneous information.

Question: "Where do amateurs need to position themselves to pirate a secret transmitted over the air?"

OPTIONS:
- no
- yes

Answer: "They need to position themselves near a company's satellite dish"

Response: yes

When you get sick, your body springs to action. Your body starts to fight the illness. Thats why you want to eat right and get plenty of sleep. You need a strong immune system to fight off illness. Plants dont have an immune system. That does not mean they do not get sick. Plants are affected by disease just like us. Typically, their first line of defense is the death of part of the plant. This prevents the infection from spreading. Many plants also produce special chemicals to fight disease. For example, willow trees produce a chemical to kill the bacteria. The same compound is used in many acne products. You can see a picture of a willow tree in Figure Plants may be smarter than we think. No, they cannot talk to each other. They may be able to send messages, though.

Question: "Can plants fight infection without releasing special chemicals?"

OPTIONS:
- no
- yes

Answer: "Yes"

Response: yes

Heat supplies the energy that causes motion. The deeper you go into toward the Earths core, the hotter it gets. At the core it is really hot. All that heat tries to rise toward the surface. In the Mantle, the rock is partially melted and is able to move. As it is heated, the material in the mantle moves toward the surface. As the mantle material rises, it cools. When it reaches the Earths crust, it is mostly stopped. A little of the material can break through the surface, but not all. Instead, it begins to move horizontally. The mantle material moves horizontally away from a mid-ocean ridge crest. Toward the surface, the mantle material starts to cool. As it cools it sinks back down into the mantle. These areas are where deep sea trench occur. The material sinks back down to the core. The system operates like a giant conveyor belt. The motion due to heating and cooling is called convection.

Question: "Why does the system work as a conveyor belt?"

OPTIONS:
- no
- yes

Answer: "Because the material moves horizontally"

Response:
no
