Read the passage carefully and choose correct answer for each question below.Education is another area of social life in which information technology is changing the way we communicate. Today's college students may not simple sit in a lecture or a library to learn about their field. Through their computers and the wonders of virtual reality they can participate in lifelike stimulated experiences. Consider the following scenario of the future of education made possible through developments in information technology.For children over the age of 10, daily attendance at schools is not compulsory. Some of the older children attend school only once or twice a week to get tutorial support or instruction from a teacher. For the most part, pupils are encouraged to work online from home.

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 .      An air pollutant is defined as a compound added directly or indirectly by humans to the atmosphere in such quantities as to affect humans, animals, vegetation, or materials adversely. Air pollution requires a very flexible definition that permits continuous change. When the first air pollution laws were established inEngland in the fourteenth century, air pollutants were limited to compounds that could be seen or smelled - a far cry from the extensive list of harmful substances known today. As technology has developed and knowledge of the health aspects of various chemicals has increased, the list of air pollutants has lengthened. In the future, even water vapor might be considered an air pollutant under certain conditions.      Many of the more important air pollutants, such as sulfur oxides, carbon monoxide, and nitrogen oxides, are found in nature. As the Earth developed, the concentration of these pollutants was altered by various chemical reactions; they became components in biogeochemical cycles. These serve as an air purification scheme by allowing the compounds to move from the air to the water or soil. On a global basis, nature's output of these compounds dwarfs that resulting from human activities.      However, human production usually occurs in a localized area, such as a city. In such a region, human output may be dominant and may temporarily overload the natural purification scheme of the cycles. The result is an increased concentration of noxious chemicals in the air. The concentrations at which the adverse effects appear will be greater than the concentrations that the pollutants would have in the absence of human activities. The actual concentration need not be large for a substance to be a pollutant; in fact, the numerical value tells us little until we know how much of an increase this represents over the concentration that would occur naturally in the area. For example, sulfur dioxide has detectable health effects at 0.08 parts per million (ppm), which is about 400 times its natural level. Carbon monoxide, however, has a natural level of 0.1 ppm and is not usually a pollutant until its level reaches about 15 ppm. The word "localized" in the third paragraph is closest in meaning to _______.

Ở một loài thực vật, màu sắc hoa là do hai gen, mỗi gen gồm 2 alen( kí hiệu A ,a và B,b) nằm trên hai nhiễm sắc thể khác nhau quy định. Trong đó khi có mặt của cả hai alen trội A và B trong kiểu hình hoa có màu đỏ, khi chỉ có một trong hai alen trội A hoặc B thì hoa có màu hồng, khi không có alen trội nào thì hoa có màu trắng. Những kết luận nào trong số các kết luận dưới đây là đúng về hiện tượng di truyền của tính trạng màu hoa 1. Khi lai hai dòng hoa hồng thuần chủng thu được F1, tiếp tục cho F1 tự thụ phấn thì ở đời F2 có thể thu được tỷ lệ phân li kiểu hình là 9:6:1 2. Cho cá thể F1 dị hợp về hai cặp gen lai phân tích thì F2 thu được tỷ lệ phân li kiểu hình là 1 đỏ: 2 hồng : 1 trắng 3. Lấy ngẫu nhiên hai cây hoa đỏ F2 sinh ra từ phép lai AaBb × AaBb lai với nhau thì tỷ lệ xuất hiện cây hoa trắng ở đời con là 1/81 4. Nếu cho cá thể F1 dị hợp về hai cặp gen tự thụ phấn thì tỉ lệ cây hoa hồng thuần chủng ở F2 là: 3/8 Tổ hợp các câu trả lời đúng là:
