Task 2.The reading passage has four paragraphs labeled A-D. Which paragraph contains the following information? You may use any letter more than once.a description of a change in whale communicationsan explanation of the purpose of fin whale communicationxamples of sources of human noisea reason why songs are necessary for some species of whalea warning about the possible dangers of human noisea description of whale communicationa location of the researcha description of artificial sounds in oceansa scientific journal specified on human relations with environmentcommunal areas of the species for breeding timeHuman noise may disturb whales' 'Love Songs'A Whales belt out the loudest songs on Earth - the slow, low ballads of blue and fin whales can be heard for several thousand miles. Researchers tracked down bellowing fin whales in the Sea of Cortez. and concluded that the songs were breeding displays to 'serenade' females because all the singers were male. B The discovery makes a lot of sense because fin whales, like blue whales, do not have breeding grounds. But they don't need them because they can locate each other with these long-distance calls. C The finding raises concerns that rising levels of ocean noise caused by commercial vessels and military sonar could interfere with these communications. Since the human contribution to ocean noise is dominated by sounds in a similar low-frequency range but produced by shipping vessels, oil and gas exploration and military activities, researchers fear the cacophony may disrupt or drown out the ocean banter of marine animals and could possibly damage their hearing. D One study published in Nature in 2015 showed that low-frequency active sonar altered the singing behavior of humpback whales. Humpback songs were associated with reproduction but it is not clear whether the alterations would affect reproduction rates or were needed to compensate for the noise. Task 1. Multiple-choice doze. For questions 1-10, read the text below and decide which answer (A,B, C or D) best fits each gap. Eg.: 0 – A 'Sorry!’ How polite are the British? An 0… stereotype suggests that the British are polite, but have you 1… asked yourself whether that's really true? Imagine two situations: in the first, you are 2… for a bus, when someone walks into you; in the second, you have 3… sat down on the Tube, when the person next to you stands on your 4 … as they are getting up. Who should say sorry – you, or the person who made the mistake? In most countries, it would be the person 5… for the mistake. However, it’s 6… more likely in the UK that both you and the person who made the mistake would apologize to 7… other! Why? The 8… may come from a recent survey in a national newspaper which found that people tend to use the word ‘sorry’ 9… and most admit to never meaning it at all. Perhaps the British are not as polite 10… we might think after all!
