Read the following passage and mark the letter A, B, C, or Don your answer sheet to indicate the correct answer to each of the questions from 30 to 34  

     The term "dyslexia” is used to describe a number of problems associated with reading, writing or spelling. Short-term memory, mathematics, concentration, personal organization and sequencing may also be affected. We do not know exactly what causes dyslexia, but we do know that it tends to run in the family. We also know that more boys suffer from dyslexia than girls and that dyslexia is more common in urban areas than in rural.  

     One of the most common signs of dyslexia is “reversals”. People with this kind of problem often confuse letters like “b” and "a" when reading and writing or they sometimes read and write words like "tip" and "won" as “pit” and “now”. Other common characteristics are lack of punctuation, misspelling, mixed-up sentence structure and poor grammatical construction.  

     People are born with dyslexia, but it is only when they begin to learn to write that it becomes a noticeable problem. For children with dyslexia, going to school can be a traumatic experience. Poor achievement can make them feel frustrated and insecure. They are reluctant to go to school and sometimes even skip school together, Cheating, stealing and experimenting with drugs can also occur when children regard themselves as failures.  

          It is a common misconception that dyslexic people are of inferior intelligence. Yet Albert Einstein, Leonardo da Vinci, Thomas Edison and Hans Christian Andersen were apparently all dyslexic. There is no total cure for dyslexia; however, the effects of dyslexia can be lessened with the guidance of skilled specialists and a lot of determination

When does it become apparent that a child may be suffering from dyslexia?

Read the following passage and mark the letter A, B, C, or D to indicate the correct answer to each of the questions from 35 to 42  

     The elements other than hydrogen and helium exist in such small quantities that it is accurate to say that the universe is somewhat more than 25 percent helium by weight and somewhat less than 75 percent hydrogen.  

     Astronomers have measured the abundance of helium throughout our galaxy and in other galaxies as well. Helium has been found in old stars, in relatively young ones, in interstellar gas, and in the distant objects known as quasars. Helium nuclei have also been found to be constituents of cosmic rays that fall on the earth (cosmicrays are not really a form of radiation; they consist of rapidly moving particles of numerous different kinds). It doesn't seem to make very much difference where the helium is found. Its relative abundance never seems to vary much. In some places, there may be slightly more of it; in others, slightly less, but the ratio of helium to hydrogen nuclei always remains about the same.  

     Helium is created in stars. In fact, nuclear reactions that convert hydrogen to helium are responsible for most of the energy that stars produce. However, the amount of helium that could have been produced in this manner can be calculated, and it turns out to be no more than a few percent. The universe has not existed long enough for this figure to be significantly greater. Consequently, if the universe is somewhat more than 25 percent helium now, then it must have been about 25 percent helium at a time near the beginning.  

          However, when the universe was less than one minute old, no helium could have existed. Calculations indicate that before this time temperatures were too high and particles of matter were moving around much too rapidly. It was only after the one-minute point that helium could exist. By this time, the universe had cooled so sufficiently that neutrons and protons could stick together. But the nuclear reactions that led to the formations of helium went on for only relatively short time. By the time the universe was a few minutes old, helium production had effectively ceased

     The elements other than hydrogen and helium exist in such small quantities that it is accurate to say that the universe is somewhat more than 25 percent helium by weight and somewhat less than 75 percent hydrogen.  

     Astronomers have measured the abundance of helium throughout our galaxy and in other galaxies as well. Helium has been found in old stars, in relatively young ones, in interstellar gas, and in the distant objects known as quasars. Helium nuclei have also been found to be constituents of cosmic rays that fall on the earth (cosmicrays are not really a form of radiation; they consist of rapidly moving particles of numerous different kinds). It doesn't seem to make very much difference where the helium is found. Its relative abundance never seems to vary much. In some places, there may be slightly more of it; in others, slightly less, but the ratio of helium to hydrogen nuclei always remains about the same.  

     Helium is created in stars. In fact, nuclear reactions that convert hydrogen to helium are responsible for most of the energy that stars produce. However, the amount of helium that could have been produced in this manner can be calculated, and it turns out to be no more than a few percent. The universe has not existed long enough for this figure to be significantly greater. Consequently, if the universe is somewhat more than 25 percent helium now, then it must have been about 25 percent helium at a time near the beginning.  

          However, when the universe was less than one minute old, no helium could have existed. Calculations indicate that before this time temperatures were too high and particles of matter were moving around much too rapidly. It was only after the one-minute point that helium could exist. By this time, the universe had cooled so sufficiently that neutrons and protons could stick together. But the nuclear reactions that led to the formations of helium went on for only relatively short time. By the time the universe was a few minutes old, helium production had effectively ceased
