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.
Genetic modification of foods is not a new practice. It has been practiced for thousands of years under the name of "selective breeding". Animals and plants were chosen because they had traits that humans found useful. Some animals were larger and stronger than others, or they yielded more food, or they had some other trait that humans valued. Therefore, they were bred because of those traits. Individuals with those traits were brought together and allowed to breed in the hope that their offspring would have the same traits in greater measure.
Much the same thing was done with plants. To produce bigger or sweeter fruit, or grow more grain per unit of land, strains of plants were combined and recombined to produce hybrids, or crossbreeds that had the desired traits in the right combinations. All the while, however, biologists wondered: is there a more direct and versatile way to change the traits of plants and animals? Could we rewrite, so to speak, the heredity of organisms to make them serve our needs better?
In the 20th century, genetic modification made such changes possible at last. Now, it was possible to alter the genetic code without using the slow and uncertain process of selective breeding. It even became possible to blend plants and animals genetically: to insert animal genes into plants, for example, in order to give the plants a certain trait they ordinarily would lack, such as resistance to freezing. The result was a tremendous potential to change the very nature of biology.
The word "them" in paragraph 2 refers to ______.
A.organisms
B.traits
C.animals
D.plants

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 35 to 42.
Public holidays in the United Kingdom, commonly referred to as bank holidays, are days where most businesses and non – essential services are closed although an increasing number of retail businesses (especially the larger ones) do open on some of the public holidays. There are restrictions on trading on Sundays and Christmas Day. Four public holidays are common to all countries of the United Kingdom. These are: New Year's Day, the first Monday in May, Christmas Day, and Boxing Day. Some banks open on some bank holidays. In Scotland, while New Year's Day and Christmas Day are national holidays, other bank holidays are not necessarily public holidays, since the Scots instead observe traditional local customs and practice for their public holidays. In Northern Ireland, once again, bank holidays other than New Year's Day and Christmas Day are not necessarily public holidays. Good Friday and Christmas Day are common law holidays, except in Scotland, where they are bank holidays. In Scotland the holiday on 1 January (or 2 January if 1 January is Sunday) is statutory, and 25 December is also a statutory holiday (or 26 December if Christmas Day falls on a Sunday). Boxing Day is a holiday traditionally celebrated the day following Christmas Day, when servants and tradesmen would receive gifts, known as a "Christmas box", from their bosses or employers. Today, Boxing Day is the bank holiday that generally takes place on 26 December. And 28 December only is given if Boxing Day is Saturday.
Like Denmark, the United Kingdom has no national day holiday marked or celebrated for its formal founding date. Increasingly, there are calls for public holidays on the patron saints' days in England, Scotland and Wales. An online petition sent to the Prime Minister received 11,000 signatures for a public holiday in Wales on St. David's Day; the Scottish Parliament has passed a bill creating a public holiday on St. Andrew's Day although it must be taken in place of another public holiday; campaigners in England are calling for a bank holiday on St. George's Day; and in Cornwall, there are calls for a public holiday on St. Piran's Day.
What is the passage mainly about?
A.Boxing Holiday in the U.K.
B.Public holidays in the U.K.
C.Weekend holiday
D.Similar holidays in Europe
