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 from 30 to 34.In today's competitive world, what responsible parent would not want to give their children the best possible start in life? For this reason, many parents want their children, often as young as ten months old, to become familiar with computers. They seem to think that if their children grow up with computers, they will be better equipped to face the challenges of the future. No one has proved that computers make children more creative or more intelligent. The truth may even be the opposite. Educational psychologists claim that too much exposure to computers, especially for the very young, may negatively affect normal brain development. Children gain valuable experience of the world from their interaction with physical objects. Ten-month-old babies may benefit more from bumping their heads or putting various objects in their mouths than they will from staring at eye-catching cartoons. A four-year-old child can improve hand-eye coordination and understand cause and effect better by experimenting with a crayon than by moving a cursor around a computer screen. So, as educational psychologists suggest, instead of government funding going to more and more computer classes, it might be better to devote resources to music and art programs.It is ludicrous to think that children will fall behind if they are not exposed to computers from an early age. Time is too precious to spend with a "mouse". Now is the time when they should be out there learning to ride a bike. There will be time later on for them to start banging away at keyboards.(Source: Internet)The word "ludicrous" paragraph 3 mostly means _____ .A.ironic B.sensible C.humorous D.ridiculous

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 from 51 to 60. The ability to conduct electricity is one of the key properties of a metal. Other solid materials such as silicon can conduct electricity but only effectively at certain temperatures. Also, some substances such as salt (sodium chloride) can conduct when molten or when dissolved in water. The ability of metals to conduct electricity is due to how their atoms bond together. In order to bond together the metal atoms lose at least one of their outermost electrons. This leaves the metal atoms with a positive charge and they are now strictly ions. The lost electrons are free to move in what is known as a sea of electrons. Since the electrons are negatively charged they attract the ions and this is what keeps the structure together.An electric current is a flow of charge and since the electrons in the sea of electrons are free to move they can be made to flow in one direction when a source of electrical energy such as a battery is connected to the metal. Hence we have an electric current flowing through the wire, and this is what makes metals such good conductors of electricity. The only other common solid conducting material that pencil users are likely to encounter is graphite (what the ‘lead’ of a pencil is made from). Graphite is a form of carbon and again the carbon atoms bond in such a way that there is a sea of electrons that can be made to flow as an electric current. Likewise, if we have an ionic substance like salt we can make the electrically charged ions flow to create a current but only when those ions are free to move, either when the substance is a liquid or dissolved in water. In its solid state an ionic substance like salt cannot conduct electricity as its charged ions cannot flow.Electrical insulators are substances that cannot conduct electricity well either, because they contain no charged particles or any charged particles they might contain do not flow easily. Water itself is a poor conductor of electricity as it does not contain a significant amount of fully charged particles (the ends of a water molecule are partly charged but overall the molecule is neutral). However, most water we encounter does contain dissolved charged particles, so it will be more conductive than pure water. Many of the problems that occur when touching electrical devices with wet hands result from the ever-present salt that is left on our skin through perspiration and it dissolves in the water to make it more conductiveWhich of the following could best serve as the title of the passage? A.Electrical Insulators B.Electrical EnergyC.Electrical Devices D.Electrical Conductivity
