Ques:Tiny monitoring devices have become an increasingly common way for scientists to study elusive animals that are difficult to track on a day-to-day basis. However, now it seems that smart. seals have caught on to the trick and are using it to their advantage to catch fish! To find out if that is true, a team of researchers from the University of St. Andrews in Scotland selected a group often young grey seals that had neither encountered the ocean nor been exposed to any kind of acoustic tags. The researchers then placed the seals one at a time, inside a pool that contained 20 foraging boxes, only two of which housed fish -- one with tags and the other without. Each seal was allowed to explore the boxes twenty separate times. In order to ensure that mammal was not depending on its memory, the fish were moved to different boxes each time. At first, there was no difference in the amount of time it took the seals to discover the tagged and untagged fish. However, after they had been in the pool a few times, they started locating the tagged fish much faster. To confirm that this indeed was the case, there searchers conducted a second experiment using two boxes -- one with pieces of fish and the other with just acoustic tags. Sure enough, the seals were all attracted to the one that was sending out signals. While this experiment involved only seals, the researchers believe that other marine mammals may also be using the information to catch prey. Sadly, predators like sharks that have been tagged by scientists may be negatively affected, as pings they emit could warn their prey of their presence. Besides potentially messing up nature's food chain, the "dinner bell" effect of the acoustic tags could also mean that the conclusions reached by previous fish studies may not be correct. Now that the secret is out, scientists will have to come up with another way to conduct their studies -- one that is not detectable by the crafty marine animals. The researchers seem to believe that sharks tagged by scientists   _  . A) may benefit from the tags B) may attract seals by mistake C) may find it hard to find prey D) may be annoyed by the emitted pings

Ques:A deal has been signed to turn by-products from a Scottish distillery into fuel for cars. In what is declared to be a world first, the Tullibardine distillery in Perthshire has linked up with a spin-out company from Napier University in Edinburgh. They plan to use bacteria to feed on the "leftovers" from the whisky making process. This will produce butanol which can be used to fuel vehicles. More than 90% of the stuff that comes out of a whisky distillery is not whisky. It is leftovers like draff and pot ales -- both produced in the early stages of the process. They are high in sugar and are currently used for things like fertiliser and cattle feed. Napier University's Biofuel Research Centre (BfRC) has already shown that the right bacteria can feed on those by-products to produce butanol--a direct replacement for vehicle fuel. Now the spin-out company, Celtic Renewables, and independent whisky producer Tullibardine have signed an agreement. Together they will apply the process to thousands of tons of the distillery's leftovers. Professor Martin Tangney, founder of Celtic Renewables, said "Our partnership with Tullibardine is an important step in the development of a business which combines two important Scottish industries -- whisky and renewables. This project shows that creative use of existing technologies can _ resources on our doorstep to benefit both the environment and the economy." Douglas Ross, managing director of Tullibardine, which spends PS250,000 disposing of its by-products every year, said "We are delighted to be partnering Celtic Renewables in this creative business, the obvious benefits of which are environmental. It takes a cost to us and turns it into something that has social as well as commercial value." The project is being supported by a grant  from the Scottish government's Zero Waste Scotland initiative. Celtic Renewables said it eventually aimed to build a processing plant in Scotland, with the hope of building an industry that could be worth PS60m a year. According to the passage,   _  will be used to take the place of petrol. A) whisky B) whisky leftovers C) butanol D) draff and pot ales
