One of the most renowned Spanish architects of all time was Antoni Gaudi. Gaudi's emergence as one of 's preeminent artists at the end of the nineteenth century marked a milestone in the art world.
Gaudi's popularity helped to bring about the acceptance and rebirth of the Catalan language, which had been banned during the literature and art. Gaudi shares his Catalonian background with two other famous Spanish artists, Pablo Picasso and Miro. The diverse ethnic background of the region greatly influenced the work of Picasso and Miro, as well as Gaudi. Thus, their works were a combination of an old history and an active, vivid imaginary world. This has sometimes been referred to as the “Catalan Mind.” Yet it was perhaps Gaudi who had the greatest talent for bringing together diverse groups, ones which others viewed as being too diametrically opposed to be capable of coming together and co-existing amicably.
This was apparent not only in the artists and other individuals who surrounded him, but also in the varied styles and techniques he employed in his architecture. Much of his work can be seen in , where his structures are known as a fine representation of modernism. He also used a great variety of color in his buildings, and this art nouveau is often associated with his own unique style of design. All of these factors are what helped put him at the forefront of art movements to come: his unique ability to take on and transform traditional Spanish elements with the emerging diverse ethnic groups, merging these with his own fertile imagination, and consequently turning these forces into some of the greatest architecture the world has ever seen.
Which of the following adjectives best describes Gaudi?
A. intolerant
B. cautious
C. narrow-minded
D. broad- minded

Many young people from disadvantaged social classes join gangs. Gangs are groups of individuals who share a common identity. Some anthropologists believe the gang structure is one of the most ancient forms of human organization. Gangs are often associated with criminal activities.
Street gangs tend to be populated with young people from low income or impoverished homes. In contrast, organized crime gangs such as the Italian-American Mafia usually occupy the middle or upper class stratum of society.
Gangs usually take over a territory in a city or suburb. They call this territory their "turf." One common criminal activity on their turf is "providing protection." This is a common style of extortion in which a gang provides protection from its own members for money.
The word disadvantaged in the passage is closet in meaning to
A. Unhappy
B. Disabled
C. poor
D. weak

In the 1940's and 1950's, biochemists strived to learn why each of the vitamins was essential for health. They discovered that key enzymes in metabolism depend on one or another of the vitamins as coenzymes to perform the chemistry that provides cells with energy for growth and function. Now, these enzyme hunters occupied center stage.
The word "strived" is closest in meaning to
A. experimented
B. tried
C. failed

The first two decades of this century were dominated by the microbe hunters. These hunters had tracked down one after another of the microbes responsible for the most dreaded scourges of many centuries: tuberculosis, cholera, diphtheria. But there remained some terrible diseases for which no microbe could be incriminated: scurvy, pellagra, rickets, beriberi. Then it was discovered that these diseases were caused by the lack of vitamins, a trace substance in the diet. The diseases could be prevented or cured by consuming foods that contained the vitamins. And so in the decades of the 1920's and 1930's, nutrition became a science and the vitamin hunters replaced the microbe hunters.
The word "incriminated" is closest in meaning to
A. eliminated
B. blamed
C. investigated
D. produced

When was the last time you saw a frog? Chances are, if you live in a city, you have not seen one for some time. Even in wet areas once teeming with frogs and toads, it is becoming less and less easy to find those slimy, hopping and sometimes poisonous members of the animal kingdom. All over the world, even in remote jungles on the far side of the globe, frogs are losing the ecological battle for survival, and biologists are at a loss to explain their demise. Are amphibians simply over-sensitive to changes in the ecosystem? Could their rapid decline in numbers be signalling some coming environmental disaster for us all?
Frogs and toads are usually poisonous.

According to airline industry statistics, almost 90 percent of airline accidents are survivable or partially survivable. But passengers can increase their chances of survival by learning and following certain tips. Experts say that you should read and listen to safety instructions before takeoff and ask questions if you have uncertainties. You should fasten your seat-belt low on your hips and as tightly as possible. Of course, you should also know how the release mechanism of your belt operates. During takeoffs and landings, you are advised to keep your feet flat on the floor. Before takeoff you should locate the nearest exit and an alterative exit and count the rows of seats between you and the exits so that you can find them in the dark if necessary.
In the event that you are forewarned of a possible accident, you should put your hands on your ankles and keep your head down until the plane comes to a complete stop. If smoke is present in the cabin, you should keep your head low and cover your face with napkins, towels, or clothing. If possible, wet these for added protection against smoke inhalation. To evacuate as quickly as possible, follow crew commands and do not take personal belongings with you. Do not jump on escape slides before they are fully inflated, and when you jump, do so with your arms and legs extended in front of you. When you get to the ground, you should move away from the plane as quickly as possible, and never smoke near the wreckage.
It can be inferred from the passage that people are more likely to survive fires in aircrafts if they…
A. read airline safety statistics.
B. wear a safety belt.
C. don’t smoke in or near a plane.
D. keep their heads low.

This frightening scenario is in part the consequence of a dramatic increase over the last quarter century in the development of once natural areas of wet marshland; home not only to frogs but to all manner of wildlife. Yet, there are no obvious reasons why certain frog species are disappearing from rainforests in the Southern Hemisphere which are barely touched by human hand. The mystery is unsett1ing to say the least, for it is known that amphibian species are extremely sensitive to environmental variations in temperature and moisture levels. The danger is that planet Earth might not only lose a vital link in the ecological food chain (frogs keep populations of otherwise pestilent insects at manageable levels), but we might be increasing our output of air pollutants to levels that may have already become irreversible. Frogs could be inadvertently warning us of a catastrophe.
Frogs are important in the ecosystem because they control pests.
