    Read the passage given below and answer the questions/complete the sentences that follow: (8 marks)

    Sniffer dog Tucker uses his nose to help researchers find out why a killer whale population off the northwest coast of the United States is on tKe decline. He searches for whale faeces floating on the surface of the water, which are then collected for examination. He is one of the elite team of detection dogs used by scientists studying a number of species including right whales and killer whales.

    Conservation canines are fast becoming indispensable tools for biologists according to Aimee Hurt, associate director and co-founder of Working Dogs for Conservation, based in Three Forks, Montana.

    Over the last few years, though, so many new conservation dog projects have sprung up that Hurt can no longer keep track of them all. Her organization’s dogs and their handlers are fully booked to assist field researchers into 2012.

    Continental drift is the hypothesis that the Earth’s continents have moved over geologic time relative to each other, thus appearing to have “drifted” across the ocean bed.The speculation that continents might have ‘drifted’ was first put forward by Abraham Ortelius in 1596. The concept was independently and more fully developed by Alfred Wegener in 1912, but his hypothesis was rejected by many for lack of any motive mechanism. Arthur Holmes later proposed mantle convection for that mechanism. The idea of continental drift has since been subsumed by the theory of plate tectonics, which explains that the continents move by riding on plates of the Earth’s lithosphere.
