On Feb. 15, 2011, an instant survey was carried out among 18 overseas postgraduate students: 11 students were male and seven were female. The purpose of the survey was to discover the views of the students on a number of matters of personal concern. The survey was conducted by means of a questionnaire given to the students to complete. There were five questions. The first question concerned favorite color, and the second, favorite number. The next three questions were all concerned with aspects of marriage. Number three looked at the ideal age to get married. Number four examined the qualities looked for in a partner. And number five asked about the ideal number of children. The main findings were as follows. Blue was the most popular color. This was followed by green and purple. There was no real significance in the choice of lucky number. About one third of the students said that they had none. 61 percent of the students selected the age group 26-30 years as ideal for marriage followed by 21-25 years. In looking at the most important qualities in an ideal partner, some respondents wanted the person to be intelligent, others chose natural, still others indicated attractive and honest. The ideal number of children was two followed by three. It is not easy to reach any definite conclusion based upon such a small sample of students from such widely different backgrounds. However, it is clear that the majority favor 26-30 as the ideal age to get married to an intelligent partner and have two children. 1.How many male and female students were involved in this instant survey?A) 11 male students and seven female students.B) Seven male students and 11 female students.C) 18 male students and 11 female students.D) Seven male students and 18 female students.2.Which question was concerned with the ideal age of getting married?A) Question number five.B) Question number four.C) Question number three.
