Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.
It used to be that people would drink coffee or tea in the morning to pick them up and get them going for the day. Then cola drinks hit the market. With lots of caffeine and sugar, these beverages soon became the pick-me-up of choice for many adults and teenagers. Now drink companies are putting out so-called "energy drinks." These beverages have the specific aim of giving tired consumers more energy.
One example of a popular energy drink is Red Bull. The company that puts out this beverage has stated in interviews that Red Bull is not a thirst quencher. Nor is it meant to be a fluid replacement drink for athletes. Instead, the beverage is meant to revitalize a tired consumer's body and mind. In order to do this, the makers of Red Bull, and other energy drinks, typically add vitamins and certain chemicals to their beverages. The added chemicals are like chemicals that the body naturally produces for energy. The vitamins, chemicals, caffeine, and sugar found in these beverages all seem like a sure bet to give a person energy.
Health professionals are not so sure, though. For one thing, there is not enough evidence to show that all of the vitamins added to energy drinks actually raise a person's energy level. Another problem is that there are so many things in the beverages. Nobody knows for sure how all of the ingredients in energy drinks work together.
Dr. Brent Bauer, one of the directors at the Mayo Clinic in the US, cautions people about believing all the claims energy drinks make. He says, —It is plausible if you put all these things together, you will get a good result. “However, Dr. Bauer adds the mix of ingredients could also have a negative impact on the body. - We just don't know at this point,” he says.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to choose the best answer for the following questions
Today, The most universally known style of trousers for both men and women is jeans; these trousers are worn throughout the world on a variety of occasions and in diverse situations. Also called levisor denims, jeans have an interesting history, one that is intermixed with the derivations of the words jeans, denims, and levis.
The word jeans is derived from the name of the place where a similar style of pants developed. In the sixteenth century, sailors from Genoa, Italywore a rather unique type of cotton trousers. In the French language, the word for the city of Genoa and for the people from that city is Genes; this name became attached to the specific style of pants worn by the sailors from this city and developed into the word jeans that today describes the descendents of Genovese sailors' cotton pants.
Similar to the word jeans, the word denim is also derived from a place name. In the seventeenth century, French tailors began making trousers out of a specialized type of cloth that was developed in the city of Nimes, France, and was known as serge de Nimes. This name for the cloth underwent some transformations, and it eventually developed into today's denim, the material from which jeans are made and an alternate name for those popular pants.
The word leviscome from name of a person rather than a place. In the nineteenth century, immigrant Levi Strauss came to America and tried his hand at selling heavy canvas to miners taking part in the hunt for gold in northern California. Strauss intended for this canvas to be used by miners to make heavy-duty tents. This first endeavor was a failure, but Strauss later found success when he used the heavy canvas to make indestructible pants for the miners. Levi then switched the fabric from brown canvas to blue denim, creating a style of pants that long outlived him and today is referred to by his name. A modern-day urban shopper out to buy some levis is searching for a close relative of the product that Strauss had developed years earlier.
