answer to each of the questions from 6 to 10.
History books recorded that the first film with sound was The Jazz Singer in 1927. But sound films, or
talkies, did not suddenly appear after years of silent screenings. From the earliest public performances in
1896, films were accompanied by music and sound effects. These were produced by a single pianist, a small
band, or a full-scale orchestra; large movie theatres could buy sound-effect machines. Research into sound
that was reproduced at exactly at the same time as the pictures - called "synchronized sound" – began soon
after the very first films were shown. With synchronized sound, characters on the movie screen could sing
and speak. As early as 1896, the newly invented gramophone, which played a large disc carrying music and
dialogue, was used as a sound system. The biggest disadvantage was that the sound and pictures could
become unsynchronized if, for example, the gramophone needle jumped or if the speed of the projector
changed. This system was only effective for a single song or dialogue sequence.
In the "sound-on-film" system, sound was recorded as a series of marks on celluloid which could be read

by an optical sensor. These signals would be placed on the film alongside the image, guaranteeing
synchronization. Short feature films were produced in this way as early as 1922. This system eventually
brought us "talking pictures".

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 11 to 17.
The cause of tooth decay is acid, which is produced by bacteria in the mouth. The acid removes
minerals from tooth enamel, allowing tooth decay to begin; the saliva in your mouth encourages
remineralization and neutralizes the acid. The rate at which bacteria in the mouth produce acid depends on
the amount of plaque on the teeth, the composition of the microbial flora, and whether the bacteria of the
plaque have been "primed" by frequent exposure to sugar. To keep your teeth healthy, a regular dental
hygiene program should be followed.
Removing plaque with a toothbrush and dental floss temporarily reduces the numbers of bacteria in
the mouth and thus reduces tooth decay. It also makes the surfaces of the teeth more accessible, enabling
saliva to neutralize acid and remineralize lesions. If fluoride is present in drinking water when teeth are
forming, some fluoride is incorporated into the enamel of the teeth, making them more resistant to attack by
acid. Fluoride toothpaste seems to act in another way, by promoting the remineralization of early carious
lesions.
In addition to a regular dental hygiene program, a good way to keep your teeth healthy is to reduce
your intake of sweet food. The least cavity-causing way to eat sweets is to have them with meals and not
between. The number of times you eat sweets rather than the total amount determines how much harmful
acid the bacteria in your saliva produce. But the amount of sweets influences the quality of your saliva.
Avoid, if you can, sticky sweets that stay in your mouth a long time. Also try to brush and floss your teeth
after eating sugary foods. Even rinsing your mouth with water is effective.
Whenever possible, eat foods with fiber, such as raw carrot sticks, apples, celery sticks, etc., that
scrape off plaque, acting as a toothbrush. Cavities can be greatly reduced if these rules are followed when
eating sweets.
