Input: Consider Input: Article: We are much happier in our new house because it has a large garden, and you know how enthusiastic we both are about gardening. When we moved in a month ago, Mary wanted to get a dog to keep out burglars. However, we finally decided that it would be cheaper to put an iron grille in front of the door and get a burglar alarm. Last week, I went to a shop and bought an alarm for just over PS200. It consists of a control unit with three smaller units. I put the control unit in the lounge and put the other units in place by the front door, back door and lounge windows. That night I soon fell asleep because I was confident that no one could get into our house undetected. At about 1:50 a.m. I woke up suddenly and heard the siren. It was like an ambulance driving right through our bedroom. I couldn't leave the siren on all night. I went downstairs in the dark. When I reached the bottom of the stairs, I switched on the light and looked around. Oh my gosh. The back door was unlocked. I rushed to lock it and it was just at that exact moment that the 'burglar' disappeared behind a curtain. Guess what? It was an ordinary house lizard .Apparently the alarm system had been made for American or European homes in which lizards are never seen. I switched the alarm off and sat down to watch. A few moments later, a lizard ran across a wall, right in front of one of the alarm units. I won't bother to finish this story but if you'd like a burglar alarm system free of charge, just let us know.

Input: Consider Input: Article: A new report says the number of foreign students at colleges and universities in the United States increased by three percent last year. This has been the first obvious increase since 2001. American schools last fall had 583,000 foreign students. The record is 586,000. That was set in 2002 after many years of gains. But after that the numbers fell. The terrorist attacks on September 11th, 2001 led to more visa requirements. Now stronger efforts are being made to get more foreign students to study in the United States. China remained in second place in front of South Korea but behind India, whichsent almost 84,000 students last fall. The number of Japanese fell sharply by nine percent, although it remained in fourth place. There were three percent drops from Indonesia and Kenya, the only African country in the top twenty last year. But there were obvious increases from Saudi Arabia, Nepal and Vietnam. The number of Saudi students more than doubled, rising to nearly eight thousand. For a sixth year, the University of Southern California in Los Angeles had the most foreign students. Columbia University in New York was second. Other schools in the top five were New York University, the University of Illinois and Purdue University. Unlike American students in other countries, who often choose history and language study, the leading area of study in the USA was business and management. Second was engineering. The new report also says more than 220,000 Americans studied in other countries. That was during the 2005-2006 school year. It was a record number, and an increase of eight and a half percent from the year before. But only five percent of them stayed for a full year.
