That is a new solution to laptop computer theft (the crime of stealing): a program that lets owners give their property a voice when it has been taken. The program allows users to displayalerts (warning)on the missing computer's screen and even to set a spoken message. Tracking software for stolen laptops has been on the market for some time, but this is thought to be the first that allows owners _ . Owners must report their laptop missing by visiting a website, which sends a message to the model: a red and yellow "lost or stolen" sign appears on its screen when it is started. Under the latest version of the software, users can also send a spoken message. The message can be set to reappear every 30 seconds, no matter how many times the thief closes _ . "One customer sent a message saying, 'You are being tracked. I am right at your door'," said Carrie Hafeman, chief executive of the company which produces the program, Retriever. In the latest version, people can add a spoken message. For example, the laptop's speakers will say: "Help, this laptop is reported lost or stolen. If you are not my owner, report me now." The Retriever software package, which costs $29.95 but has a free trial period, has the functions of many security software programs. Owners can remotely switch to an alternative password immediately if they fear that the thief has also got hold of the access (, ) details. If a thief accesses the Internet with the stolen laptop, Retriever will collect information on the Internet service provider in use, so that the police can be alerted to its location. Thousands of laptops are stolen every year from homes and offices, but with the use of laptops increasing, the number stolen while their owners are out and about has been rising sharply. Other security software allows users to erase data remotely or lock down the computer. Question: Which of the following can best sum up the main idea of the passage? - With no Retriever, thousands of laptops are stolen every year. - A new software provides a means to reduce laptop theft. - Retriever has helped to find thieves and lost computers. - A new program offers a communication platform with the thief.

Read the following article and select the best answer. Article: According to a study by SallieMae, 84 percent of undergraduate students have credit cards, and by the time they are seniors, they have accumulated US $ 4,100 in debt, on top of whatever student loans they may have taken out. Credit cards are the most convenient form of payment, and they are aggressively marketed to college students.Reportedly, a typical college student carries 4.6 credit cards and US $ 3,173 in credit card debt. Credit cards seem to be a fact of life, not just student life. In the long term, using a credit card properly and paying off the balance can help establish a card history and increase your credit score, which will _ when you need an important loan, for a house or car, for example.Your credit score can affect even unrelated things like insurance rates.Credit cards also offer more protection for users than debit cards .Under federal law, the credit card holder is only responsible for the first US $ 50in fraudulent purchases in cases of theft or loss.However, debit card users are responsible for the first US $ 500. SallieMae found some good news in the fact that two thirds of students had discussed credit issues with their parents, but 84 percent said they needed more information.Those who didn't get any guidance were more likely to be surprised when they found out how much they owed. While credit cards offer the easiest access to money, they make it easy to live outside your means.Less than a fifth of students surveyed paid off their balance every month, and carrying a balance brings finance charges, sometimes at a very high interest rates. SallieMae found that almost 40 percent of students chose their first credit card based on direct mail, which is probably why students get credit card offers in the mail. But when the credit card offers flow in, be sure that you read the fine print.Offers of low or no interest rates can disappear, leaving you a debt that climbs beyond your ability to pay it off. Question: According to SallieMae, what is the possible reason why students get so many credit card offers in the mail? - Many students' first credit card is based on direct mail. - it costs the banks little to mail out credit cards. - Students don't like to go to the bank to open a credit card account. - Banks have no other way to let students use their credit cards.
Many students' first credit card is based on direct mail.

Q: Read the following article and select the best answer. Article: The largest earthquake ( magnitude 9.5) of the 20th century happened on May 22, 1960 off the coast of South Central Chile. It generated one of the most destructive Pacific-wide tsunamis . Near the generating area, both the earthquake and the tsunami were very much destructive, particularly in the coastal area from Concepcion to the south end of Isla Chiloe. The largest tsunami damage occurred at Isla Chiloe---the coastal area closest to the epicenter . Huge tsunami waves measuring as high as 25 meters arrived within 10 to 15 minutes after the earthquake, killing at least two hundred people, sinking all the boats, and flooding half a kilometer inland. There was large damage and loss of life at Concepcion, Chile's top industrial city. Near the city of Valdivia, the earthquake and following aftershocks generated landslides which killed 18 people. At the port city of Valparaiso, a city of 200,000, many buildings collapsed. A total of 130,000 houses were destroyed --- one in every three in the earthquake zone and nearly 2,000,000 people were left homeless. Total damage losses, including to agriculture and to industry, were estimated to be over a half billion dollars . The total number of death related with both the tsunami and the earthquake was never found accurately for the region. Estimates of deaths reached between 490 to 5,7002 with no distinction as to how many deaths were caused by the earthquake and how many were caused by the tsunami. However, it is believed that most of the deaths in Chile were caused by the tsunami. Question: What is the total number of deaths in the earthquake? - 2,000,000 - between 490 to 57,002 - 200,000 - it was hard to know.
A: it was hard to know.
