Read the passage and answer the following question.

Autism is a brain development disorder that impairs social interaction and communication and causes restricted and repetitive behavior, all starting before a child is three years old. The genetics of autism are complex and it is generally unclear which genes are responsible for it. Autism affects many parts of the brain but how this occurs is also poorly understood. Autism is strongly associated with agents that cause birth defects. Other proposed causes, such as childhood vaccines, are controversial and the vaccine hypotheses lack convincing scientific evidence. The number of people known to have autism has increased dramatically since the 1980s. Parents usually notice signs in the first two years of their child’s life. Early behavioral cognitive intervention can help children gain self-care, social and communication skills but there is no cure for it. Few children with autism live independently after reaching adulthood, but same become successful and an autistic culture has developed, with same seeking a cure and others believing that autism is a condition rather than a disorder.

Q. It can be understood from the passage that

Read the passage and answer the following question.

Researchers suggest that there are creatures that do not know what light means at the bottom of the sea.They don’t have either eyes or ears; they can only feel.There is no day or night for them. There are no winters, no summers, no sun, no moon, and no stars. It is as if a child spent its life in darkness in bed, with nothing to see or hear. How different our own life is! Sight shows us the ground beneath our feet and the heavens above us – the sun, moon, and stars, shooting stars, lightning, and the sunset. It shows us day and night. We are able to hear voices, the sound of the sea, and music. We feel we taste, we smell. How fortunate we are!

Q. Judging from the passage, we can say that this story is mainly about?

Read the passage and answer the following question.

It has frequently been argued that freeing schools from the rigid rules, regulations, and statutes that have traditionally fettered them would have a revolutionary effect on academic achievement. For instance, it has been suggested that schools embodying this idea could develop more effective teaching methods that could then be replicated in other schools. Character schools public schools that operate under a contract, or “charter” were given just such an opportunity beginning in 1991 when Minnesota passed the first charter school law. At that time, many critics warned of deleterious rather than beneficial effects that such freewheeling schools could have on the academic achievement of students. Thus, while public opinion differed concerning the social desirability of charter schools, most agreed that there would be a pronounced effect.

Surprisingly, educators who study educational reform now seriously question the degree to which charter schools have made an impact. That conclude that freedom from many of the policies and regulations affecting traditional public schools and the concomitant control over decisions that guide the day – to – day affairs of the School have not resulted in equally dramatic changes in student’s academic performance. In some state performance standards than traditional public schools. It is, however, impossible to know whether this difference is due to the performance of the schools, the prior achievement of the students, or some other factor.

Metrics for educational accountability have changed considerably in the past decade, moving increasingly to performance as measured by state mandated tests of individual student achievement. Fundamentally, however, the challenging conditions under which schools operate, be they traditional or charter, have changed little: the struggle for resources, low pay for teachers, accountability to multiple stakeholders, and the difficulty of meeting the educational requirements for children with special needs all persist.

Q. Which of the following statements best summarizes the main point of the passage?

Read the passage and answer the following question.

Unemployment was the overriding fact of life when Franklin D. Roosevelt became president of the United States on March 4, 1933. An anomaly of the time was that the government did not systematically collect statistics of joblessness; actually it did not start doing so until 1940. The Bureau of Labor Statistics later estimated that 12,830,000 persons were out of work in 1933, about one-fourth of a civilian labor force of more than 51 million.

Roosevelt signed the Federal Emergency Relief Act on May 12, 1933. The president selected Harry L. Hopkins, who headed the New York relief program, to run FERA. A gifted administrator, Hopkins quickly put the program into high gear. He gathered a small staff in Washington and brought the state relief organizations into the FERA system.

While the agency tried to provide all the necessities, food came first. City dwellers usually got an allowance for fuel, and rent for one month was provided in case of eviction.

Q. This passage is primarily about…

Read the passage and answer the following question.

Theories are divided about the cause of the Permian mass extinctions. Some hypothesize that the impact of a massive asteroid caused a sudden disappearance of species. However, a look at the carbon – isotope record suggests that existing plant communities were struck down and re – found several times. To produce such a pattern would require a succession of asteroid strikes thousands of years apart. Other theorists have proposed that volcanic explosions raised the Corban dioxide level leading to intense global warming. One problem with this theory is that it cannot explain the massive marine extinctions at the end of the Permian period. A new theory posits that rising concentrations of toxic hydrogen sulfide in the world’s oceans plus gradual oxygen depletions in the surface waters caused the extinctions in the surface waters caused the extinctions. Fortunately, this theory is testable. If true, oceanic sediments from the Permian period would yield chemical evidence of a rise in hydrogen sulfide – consuming bacteria.

Q. The primary purpose of the passage is to

Read the passage and answer the following question.

Grossly misunderstood and represented as a revolutionary, liberal, Romantic, and bohemian artist, Rembrandt has lived for over 400 years now through his art. During this time period, many views and opinions have oscillated from praise to scathing remarks and vice versa.

The extent of Rembrandt’s fame can be understood by the following incident: in the year 1670, the Sicilian collector Antonio Ruffo received a letter from the artist Abraham Breughel with a request to get some original masterpieces from Italy. Ruffo had to apologize stating that no painter had been able to exhibit an ability to paint as extraordinary as Rembrandt, who had already died by then.

Q. Which of the following, most accurately summarizes the opinion of the author in the text?

Read the passage and answer the following question.

Stump-Up was invented in 1986 by Tokyo Beverages Owner Okawa Bhery. The name for the product was actually proposed by Okawa’s assistant, Fizzy Brewndon. The name was taken from the two most unusual ingredients in the drink, the Canadian banana leaf and the Asian stump root. The recipe for today’s Stump-Up is very well guarded. Many of the ingredients are known; in addition to banana leaves and stump root, they include strawberry, cocoa, lemon, cinnamon, nuts, vanilla, caramel, salts and sugar. The proportions of the ingredients and the identity of Stump’s secret ingredients are known by only a few of the Stump-Up Company’s very senior scientists and Vice-Presidents.

Q. It can be inferred from the passage that

Read the passage and answer the following question.

Jupiter has 2.5 times more mass than all the other planets of the solar system combined and is 11 times as large as Earth in diameter. Jupiter is so large that scientists believe it almost became a star: as the gasses and dust contracted to the form the planet, gravitational forces created tremendous pressure and the temperature inside the core—as high as tens of thousands of degrees. But there was not enough mass available to create the temperature needed to start a fusion reaction such as that of the Sun (above 27,000,000 Fahrenheit, or 15,000,000 Celsius, at the Sun’s core); thus Jupiter has been cooling down ever since. Even so, Jupiter radiates about as much heat as it receives from the Sun.
