One famous sunken ship is the “Lusitania”, which sank off the southern coast of Ireland in 1915 with a loss of nearly, 1,500 lives. It has four huge propellers made of an expensive metal. Today each of those propellers is worth $ 300,000 or more. The ship lying on the sea-bed has been brought by a man called John Light. He paid about $ 1,200,000 for the whole ship. He hopes to bring up those propellers and sell them. He also hopes to sell other parts of the ship, when he has brought them to the surface, for about $ 600,000.

Questions 16-20 are based on the following passage:
No antibiotics have been proved to be 100% effective in treating SARS so far. The only effective way to get rid of it is by ourselves. It likes a prolonged battle between the viruses and our immune response. In fact, viruses couldn´t kill all the immune cells in a health individual. The stronger the immune function you have, the less the viral injury you get. Therefore, the degree of sickness after infection and the rate of recovery mainly depend on how strong your immune function is.
You cannot avoid the infection unless you avoid from those infected individuals/area. But, you can try your best to boost up your immune function by several regimes. Make sure you are “extremely healthy” at least during this critical period. Stronger immune function could keep the viral damage minimal even you were so unluckily being infected. Also, stronger immune function delays the onset of any detrimental effects from the viral infection. Scientists are now working on tracking the treatment fixing all sorts of flaws in DNA and so make sure you are still surviving until an effective treatment occurs.
