Article: Store shelves are filling up with so-called "green" products promising to benefit the environment. A recent argument shows that it can be as difficult for buyers to confirm such statement as for producers to defend them. The argument concerns the GreenPlug Electricity Saver. The GreenPlug is supposed to prevent energy waste by electrical equipment whose constant -speed motors operate at less full load---as is especially true of older refrigerators. Research showed that such motors can be made to do the same work with less heat, noise, and power consumption just by lowering the voltage of the power supply. John and Wyck Hay, started Green Technologies to apply that finding to home appliances. In the USA, there are more than 140 million refrigerators in use, accounting for an average of 16% of the household electric bill. Two years of research resulted in the GreenPlug. Connecting between wall socket and refrigerator, the equipment contains a minicomputer that gives a motor full power (120 volts on average) for start-up, then reduces the power to 106 volts. Older refrigerators are the most overpowered and, thus, save the most energy with a GreenPlug. Refrigerators less than two years old are already energy-saving that a GreenPlug actually makes them waste electricity. The higher the voltage, the larger the difference a GreenPlug makes. Higher power costs shorten the payback time. The population-weighted national average is 10 cents per kilowatt-hour. But some residents in Washington State pay 1.5 cents. Some in Alaska pay 41.6 cents. Then come highly individual household differences like the number of children or refrigerator -opening age. All in all, the GreenPlug should save the average consumer $20 a year. Although the GreenPlug lowered the voltage as it was designed to do,Consumer Reports, an influential magazine, questioned how quickly---if ever---electricity savings due to the plug would repay its cost. People would be better off buying a new, high-efficiency refrigerator, the magazine... Question: In the GreenPlug argument, the magazine Consumer Reports _ . Yes or no, is the answer "doubts the effect of the GreenPlug"?
No

Article: Most people have heard the sound of bees among flowers. Bees live almost everywhere in the world except in the Arctic areas. Many kinds of agriculture depend on these small, social insects. Without bees, fruit and nut growers as well as many other farmers would not have a crop. There are more than 20,000 kinds of bees. But only honey bees make enough honey for people to use. Honeybees are highly-organized social insects. They work together in a group, called a colony . Each colony lives in a hive . It contains one queen bee -- she lays all the eggs from which the members of the colony come. Each colony has only a few hundred males, called drones. The majority of all bees in a colony are workers, which are all females. Bees even have a special stomach, called a honey stomach, which is used to store sweet fluid that the bees gather from flowers. Bees also have long hairs on their body and legs. These hairs capture pollen as bees go from flower to flower. Some of the pollen is taken back to the hive. Some, however, is passed to the next flower. This is how many plants are fertilized. Pollen is the reproductive material of plants. Many important agricultural crops depend on bees for fertilization. Inside their hives, bees store sweet liquid from flowers and pollen as well. They may even gather sweet liquid from some other kinds of insects. These kinds of sweet liquid are also stored in the hive. Bees make honey through a process. They add liquid from their own mouths to sweet liquid into simple sugar. As the honey is stored, it dries. It becomes thicker and darker. Although bees are often thought of as honey makers, they provide a surprising number of products. Also, their greatest economic value is in fertilizing crops-not in making honey. Question: The word "fertilize" in the sentence "This is how many plants are fertilized" probably means " _ ". Yes or no, is the answer "to introduce pollen into plants"?
Yes
