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.

The Singapore Science Centre is located on a six-hectare site in Jurong. At the centre, we can discover the wonders of science and technology in a fun way. Clap your hands and colorful bulbs will light up. Start a wheel spinning and it will set off a fan churning. It is a place to answer our curiosity and capture our imagination.

The centre features over four hundred exhibits covering topics like solar radiation, communication, electronics, mathematics, nuclear energy and evolution. It aims to arouse interest in science and technology among us and the general public. The centre is the first science one to be established in South East Asia. It was opened in 1977 and it now receives an average of one thousand, two hundred visitors a day. The exhibits can be found in four exhibition galleries. They are the Lobby, Physical Sciences, Life Sciences and Aviation. These exhibits are renewed annually so as to encourage visitors to make return visits to the centre.

Instead of the usual “Hands off’ notices found in exhibition halls, visitors are invited to touch and feel the exhibits, push the buttons, turn the cranks or pedals. This is an interesting way to learn science even if you hate the subject. A Discovery Centre was built for children between the ages of three and twelve. This new exhibition gallery was completed in 1985. Lately this year a stone-age exhibit was built. It shows us about the animals and people which were extinct.

It is indicated in paragraph 3 that ______.

A. if you hate science you will never learn the subject even you visit the centre 

B. children under 3 are not allowed to visit the centre 

C. it is impossible for visitors to touch and feel the objects in the centre 

D. the “Hand off” notice is not found in the centre

Legend has it that sometime toward the end of the Civil War (1861-1865) a government train carrying oxen traveling through the northern plains of eastern Wyoming was caught in a snowstorm and had to be abandoned. The driver returned the next spring to see what had become of his cargo. Instead of the skeletons he had expected to find, he saw his oxen, living, fat, and healthy. How had they survived?

The answer lay in a resource that unknowing Americans lands trampled underfoot in their haste to cross the “Great American Desert” to reach lands that sometimes proved barren. In the eastern parts of the United States, the preferred grass for forage was a cultivated plant. It grew well with enough rain, then when cut and stored it would cure and become nourishing hay for winter feed. But in the dry grazing lands of the West that familiar bluejoint grass was often killed by drought. To raise cattle out there seemed risky or even hopeless. Who could imagine a fairy-tale grass that required no rain and somehow made it possible for cattle to feed themselves all winter? But the surprising western wild grasses did just that. They had wonderfully convenient features that made them superior to the cultivated eastern grasses. Variously known as buffalo grass, grama grass, or mesquite grass, not only were they immune to drought; but they were actually preserved by the lack of summer and autumn rains. They were not juicy like the cultivated eastern grasses, but had short, hard stems. And they did not need to be cured in a barn, but dried right where they grew on the ground.

When they dried in this way, they remained naturally sweet and nourishing through the winter. Cattle left outdoors to fend for themselves thrived on this hay. And the cattle themselves helped plant the fresh grass year after year for they trampled the natural seeds firmly into the soil to be watered by the melting snows of winter and the occasional rains of spring. The dry summer air cured them much as storing in a barn cured the cultivated grasses.

The word “preferred” in line 8 is closed in meaning to________.

A. favored

B. available

C. ordinary

D. required
