Which of the following is NOT mentioned as a means by which an orchid attracts insects?
A. Size.
B. Shape.
Color.
D. Scent.
To lure their pollinators from afar, orchids use appropriately intriguing shapes, colors, and scents. At least 50 different aromatic compounds have been analyzed in the orchid family, each blended to attract one, or at most a few, species of insects or birds. Some orchids even change their scents to interest different insects at different times.
Once the right insect has been attracted, some orchids present all sorts of one-way obstacle courses to make sure it does not leave until pollen has been accurately placed or removed. By such ingenious adaptations to specific pollinators, orchids have avoided the hazards of rampant crossbreeding in the wild, assuring the survival of species as discrete identities. At the same time they have made themselves irresistible to collectors.
The orchid is unique because of______.
A. the habitat in which it lives
B. the structure of its blossom
C. the variety of products that can be made from it
D. the length of its life
PART C

听力原文: The piano and violin are girls' instruments. Drums and trumpets are for boys. According to Psychologists Susan O'neil and Michael Bottome, children have very clear ideas about which musical instruments they should play. They found that despite the best efforts of teachers, these ideas have changed very little over the past decade. They interviewed 153 children, aged between 9 and 11, from schools in northwest England. They asked them to identify four musical instruments and then say which they would like to play most and which they would least like to play. They also asked the children for their views on whether boys or girls should not play any of the four instruments. The piano and violin were both ranked more favorably by girls than by boys, while boys preferred the drums and trumpets, There was a broad agreement between boys and girls on which instruments each sex should play and the masons varied. And while almost half of all boys said they avoided certain instruments because they were too difficult to play. Only 15 percent of girls gave that as a reason. Earlier studies indicated that very young school children aged between 5 and 7, showed no bias in choosing musical instruments. But their tastes become more clear between the ages of 8 and 10. One survey of 78 teachers suggested that after that age, both boys and gifts begin to restrict themselves to the so-called male or female instruments.
How many children did Susan and Michael interview?
A. 150.
B. 151.
C. 152.
D. 153.
