Question 1
Question 2
Question 3 An important reason for ants' success is their ability to talk-not with words but with tastes and smells. Their vocabulary is made up of a mixture of substances they produce in various parts of their bodies and emit via their glands. The so-called pheromones are signals that other ants can smell and taste. The messages they communicate set off a 5 specific kind of behaviour: fetching food for instance or looking after the brood or feeding the queen. Furthermore, ant-talk is not limited to food. Ants use a hundred different scents to communicate a hundred different messages. With such a sophisticated array of messenger fragrances, ants organize complicated tasks with close-to-perfect sefficiency. 10 Every ant is a specialist with a vocation of its own. The queen has one of the biggest workloads-laying eggs round the clock. Despite the presence of a queen, an ant colony is not a monarchy. The word 'queen' is actually a misnomer. "She doesn't reign over the others," says Holldobler. "She's a machine for laying eggs. "From morning till night she produces her daughters, 15 the sterile workers of the colony. Males don't have to do much and the queen only produces them when reproduction time is approaching. Their main job is to fertilize the winged females. After that they die. Messengers don't have much free time either. When you see a handful of ants scurrying around in the kitchen without any apparent purpose, 20 it doesn't mean they have lost their bearings. They're scouts foraging for food. Once they've found something edible, they report back to base, depositing their chemical spores on the way. "Food located, please collect," is the taste and smell message for the other members back at the nest. 25 Very soon, long chains of worker-ants begin scurrying back and forth from their nest ferrying food which they hand over to ants who specialize in housekeeping. The duties of these ants include keeping the nest in good order and cleaning and feeding the queen. Jet ants settle in hollow trees where they build papery structures to 30 live in. In these trees they keep herds of greenflies which they actually milk in the same way we milk cows. It's a model partnership. To satisfy their need for amino acids, the greenflies have to ingest large quantities of sap. As a result, surplus sugar forms in their bodies which they excrete through their rear ends. This so-called 35 honeydew is the jet ants' main source of nourishment. In return, the ants see to it that the greenflies don't get stuck fast in their own honey and also protect their herds from marauding predators such as ladybirds. "It's a form of dairy farming," says Holldobler. Dairying is only one of the many ingenious ideas ants have come up 40 with in the course of evolution. Small red wood ants, for example, regulate the temperature in their high-rise ant hills by sunbathing on warm spring days and then scuttling back to the nest double quick to give off the warmth they've soaked up. An ant colony, Holldobler says, is an almost perfectly organized 45 network of equal status elements complementing one another in all they do. Ants will do anything as long as it's in the service of the common weal. "May be socialism does work after all under certain circumstances," Holldobler grins. "Karl Marx just had the wrong species in mind."49 (a) Five words are given below. Give the meaning of each word as used in the passage. One word answers or short phrases will be accepted.
