Read the following article and answer the question. 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: We can infer from the passage that the author _ . Answer:
OPTIONS:
- feels optimistic about the future of GreenPlug.
- believes the GreenPlug has cheated customers.
- holds an objective attitude to the issue.
- encourages further investigation.
holds an objective attitude to the issue.

Read the following article and answer the question. Article: When his book Little Princes began, Conor Grennan was planning a year-long trip around the globe, a journey that began with a three-month volunteer service at the Little Princess Children's Home, an orphanage in Nepal. Arriving there, Conor was immediately welcomed by all the children even though he had no previous experience in working with children. He quickly grew to love the job. But it wasn't long before Conor came to learn that the children were not orphans at all--they were actually children who had been separated from their parents by a child trafficker . This realization turned Conor's global journey into a strong desire to try to find a way to reunite these children with their families. As a part of his efforts, Conor did a great amount of work when he was back in America. He started up a nonprofit organization called Next Generation Nepal (NGN), raising funds in order to buy a house in Nepal for another children's home. Then, back in Nepal, he began a life-changing trip into remote villages. It is really amazing to read about Conor communicating with the children and to read his descriptions of each of them. He made me truly care about the kids. I wanted them to be able to reunite with their families, too! Unfortunately, this was simply not possible for some of the children. But there were some lucky ones. Jagrit, for example, had thought for years that both his parents were dead. So, Conor was surprised when he visited Jagrifs village and was introduced to the boy's father! Conor successfully found many of the families of the children and also found his future wife while in Nepal. Question: What do we know about Little Princess Children's Home? Answer:
OPTIONS:
- Many children ended there due to illegal trade.
- The children in it are all orphans.
- It is a worldwide profitable organization.
- It has many branches all over Nepal.
