Due to the increasing number of violence acts produced in schools all over the world, more and more parents prefer to have their children educated at home rather than at school. This way they can ensure their safety and well-being, although teachers and school representatives are trying to improve the situation in schools by increasing the number of the persons in charge of the safety of the students. The main reason for violence acts are the films and cartoons that fill the children's time. They want to do everything they watch on TV and never think of the consequences, and they may hurt a classmate or a teacher. On the other hand, parents are not fully satisfied with the children's results obtained in classes and they consider private classes would have better results. When a teacher has to watch 30 students in class he can't probably see what each of them is doing, how he is writing, or if he understands the explanations. At home the teacher can explain in details everything the child doesn't understand as many times as he considers proper. And many times the child grows fond of the teacher at home, who becomes his best friend, and who helps him whenever he needs someone to talk to. However, the best solution would be a mixture between the education received at school and that at home, because school makes children communicate and socialize. Keeping a child at home for fear there might happen something bad to him only makes the child's character weak and prevents him from knowing what real life is. Staying in _ only does harm to the child. All in all, schools have been created to help children, not to harm them, so it's best to keep children in these special places, where they learn, laugh, have fun and make new friends We can infer from the passage that _ . A) violence TV programs have bad effects on children's behavior B) the teacher at home is more patient than the teacher at school C) children today are weak from lack of sense of right and wrong D) there are too many students in class for a teacher to teach

(Question)
An antifreeze is a liquid that is added to water to keep it from freezing. When water freezes and turns to ice, it expands. The force of water expanding is so great that it will break the hardest metal. Water is used in car engines to keep them cool while they run, and if this water is allowed to freeze in winter it can break the iron block of the engine. That is why antifreezes are necessary. Water freezes at the 0degC: the usual kind of antifreeze will not freeze until the temperature is 40degC below zero. A mixture of 5 parts of water and 4 parts of antifreeze will prevent freezing at 18degC below zero; 4 parts of water and 5 parts of antifreeze reduce this to 22degC below zero. Alcohol is a good antifreeze, but when the car is running it becomes hot and the alcohol boils away, so it must be replaced very often. Most people use antifreezes that do not boil away when the engine is running. There are several chemicals that do this. One of the most popular is called ethylene glycol , which is sold under various trade names such as Preston and Zerex. The text is written _ . A) to help to sell antifreezes B) to explain what antifreezes are C) to compare ethylene glycol with alcohol D) to tell how to choose the best antifreeze

Ques: Imagine a picnic dinner held at a location only made known hours before the meal, where guests are invited to decorate tables and chairs, bring their favorite dishes and wear white to reflect the simplicity of the event. This was the scene at a PopUp dinner held on June 13 in Brooklyn, New York's Prospect Park. PopUp dinners are popping up nationwide -- not just in Brooklyn. Garrett Sathre and his wife and business partner, Nicole Benjamin-Sathre are the team behind Hand Made Events and the creators and hosts of PopUp dinners. Sathre, a former restaurateur and head chef with Bubba's Diner and Kitchen 39, both located in the Bay Area, came up with the concept of the flash dinner after he was inspired by the annual Diner en Blanc held in Paris. In 2011, Hand Made Events used the power of social media to get the word out and soon, enough interest was attracted. In October 2011, it held its first flash dinner, calling the evening Le Diner a San Francisco at Golden Gate Park's outdoor Music Pavilion. He described it as a picnic dinner for 3,500 people."I thought we would have anywhere between 300-500 people to attend. Two articles ran a week later about my crazy idea and we got 15,000 emails within three days,"Sathre said. After the success of the San Francisco dinner, Sathre decided to expand his"crazy idea"and hold dinners across the country in major markets such as Brooklyn, Los Angeles and San Francisco. Sathre says their Brooklyn PopUp on June 13 sold 5,000 tickets in just four days with 5,000 on the waiting list raising over $160,000 in ticket sales. Those are some big numbers. Hand Made Events partners with the Prospect Park Alliance and gives all of their proceeds to the non-profit group. In total, the Brooklyn PopUp dinner raised over $60,000 for the Prospect Park Alliance. Hand Made Events sees the same interest in their smaller city locations."We have seen a 30 percent increase in our smaller markets -- Minneapolis, San Diego, Charleston, and Miami every year,"Sathre said. Hand Made Events has eight... What is the main idea of this passage? A) A new kind of cooking culture has spread worldwide on social media.

Question: While every dog owner knows their dogs can read their moods perfectly, scientists have always been a piffle doubtful.Now thanks to some researchers at the University of Veterinary Medicine in Vienna, Austria; we finally have some convincing evidence. For their study, biologist Corson Miller and his team exposes eleven selected dogs to digital images of women that were either angry or happy.Half the dogs were rewired for touching the screen when shove a happy face, while the other half gilt their treat for selecting those that appeared angry. Interestingly, the dogs were not provided with the entire face.Some dogs were show Ti only upper halves while the others observed lower halves.That's because the scientists believe humans show their eruptions on their equities face. After some training ill.e how to recognize small differences like the wrinkles between the eyes or the changes in their shape that accompany the happy or angry expressions, the dogs were mostly able to identify the correct expression not only on a familiar face but on a strange face, the researchers concluded the dogs were smart-enough to read human emotions. They also found those being trained to read angry expressions took a longer time to learn.They guess it may be because dogs find angry faces disgusting, causing them to withdraw quickly.However, once the smart dogs realized they were getting rewired, the trepidation seem end to disappear.In fact, the dogs had such a good time playing the computer "game" That scientists had a hard time keeping them away from the touch screens after the study was completed. The researchers also noticed only dogs with a male owner had a harder time understanding the expressions correctly.Since the touches careen models were all females, this confirmed what has been observed in previous studies-dogs are more efficient at reading facial expressions of people that are the serene gender as their owner. How might the results change if the dogs with female owners are shown pictures of male faces? A) They could only tell commotions on partial faces rather than on entire face's. B) They found it hard to tell the moods on the faces of a different gender. C) They found it easy to tell the emotions on the entire -face. D) They would be scared away at the sight of the pictures.
