Article: Conservationists have unveiled plans to preserve and protect the world's most important species of coral, in a response to increasing threats that they say will lead to "functional extinction" within decades. Led by scientists at the Zoological Society of London, the Edge Coral Reefs project has identified 10 coral species in most urgent risk of becoming extinct.The scientists say that reefs are under pressure from a variety of threats including rising sea temperatures due to climatic instability, increased acidity , overfishing and pollution. The Edge plan, which focuses on the most evolutionarily distinct and globally endangered species , will take a regional approach to conservation.This means focusing on the "coral triangle" around the Philippines, the West Indian Ocean around the Mozambique channel, and in the Caribbean channel. "Coral reefs are threatened with functional extinction in the next 20-50 years, due predominantly to global climatic instability," said Catherine Head, coordinator of the reefs project."In these regions, we'll be supporting and training in-country conservationists to carry out research and implement targeted conservation actions," she said."Their projects will last initially for two years.We provide them with a whole host of tools to carry out their projects including funding and intensive training." She added. Coral reefs are the planet's most diverse marine ecosystem , known as the rainforests of the oceans.Despite taking up under 0.2% of the ocean floor, they provide food and shelter for almost a third of all sea life.If we lose the ecosystems, we lose not only the biodiversity , but we also lose the capability of people to obtain income and food from coral reefs. Climatic instability, which leads to rising sea temperatures, causes corals to bleach.Bleaching occurs when sea temperatures rise and this causes the coral tissue to expel their symbiotic algae called zooxanthellae - these are what give the coral their colour.Bleached corals often die if the stress continues.Among... Question: What will probably happen to coral species with the increasing threats? Answer:
OPTIONS:
- Decrease.
- Losing functions
- Disappearance.
- Existence
output: Disappearance.

Article: When prehistoric man arrived in new parts of the world, something strong happened to the large animals; they suddenly became extinct. Smaller species survived; the large, slow-growing animals were easy game, and were quickly hunted to extinction. Now something similar could be happening in the oceans. That the seas are being over-fished has been known for years and researchers such as Ransom Myers and Boris Worm have shown how fast things are changing. They have looked at half a century of data from fisheries around the world. Their methods do not attempt to estimate the actual biomass (the amount of living biological matter) of fish species in particular parts of the ocean, but rather changes in that biomass over time. According to their latest paper published in Nature, the biomass of large predators (animals that kill and eat other animals) inanes fishery is reduced on average by 80% within 15 years of the start of exploitation. In some long-fished areas, it has halved again since then. Dr. Worm acknowledges that these figures are conservative . One reason for this is that fishing technology has improved. Today's vessels can find their prey using satellites and sonar, which were not available 50 years ago. That means a higher proportion of what is in the sea is being caught, so the real difference between present and past is likely to be worse than the one recorded by changes in catch sizes. In the early days, too, longlines would have been more saturated with fish. Some individuals would therefore not have been caught, since baited hooks would have been available to trap them, leading to an underestimate of fish stocks in the past. Furthermore, in the early days of longline fishing, a lot of fish were lost to sharks after they had been hooked. That is no longer a problem, because there are fewer sharks around noise. Dr. Myers and Dr. Worm argue that their work gives a correct baseline, which future management efforts must take into account. They believe the date support an idea current among marine... Question: We can infer from Dr Myers and Dr. Worm's paper that _ . Answer:
OPTIONS:
- the stock of large predators in some old fisheries has reduced by 90%
- there are only half as many fisheries are there were 15 years ago
- the catch sizes in new fisheries are only 20% of the original amount
- the number of larger predators dropped faster in new fisheries than in the old
output: the stock of large predators in some old fisheries has reduced by 90%

Article: Left unfettered , Anthony Konieczka, 9 years old, would happily play his Game Boy Advance or PlayStation 2 from the minute he gets up to the moment he goes to bed, 14 bleary-eyed hours later. Anthony's box is stocked with traditional toys--board games, puzzles, art supplies--and as far as he is concerned, they are relics of Christmases past. His sister Michaely, 6 years old, still likes dressing her Barbies. But once she starts playing Game Boy, it's hard to get her away. Play patterns like this could take up another Christmas for the toy department. Through September, toy sales were down 5% compared with the first nine months of last year, according to the NDP Group. Meanwhile, the video-game industry is heading for another record year. Thanks to hot new games like Halo 2 for the Xbox, the industry is light-years ahead of the toy business when it comes out. While some new toys emerge every holiday season, toymakers are heading into this one without a monster hit . Indeed, there has not been a Furby-style frenzy in years. Of 10 toy segments only two, arts and crafts and dolls, have generated sales growth over a recent 12-month period. Some of the weakest categories like construction sets and action figures are the ones aimed at boys, who suffer the most from the video games. Analysts expect one of the top stocking stuffers this season to be not a traditional toy but the new generation of Nintendo's Game Boy, the DS, which hit stores last week. The deeper issue is that shifts in play patterns are forcing toymakers to fight for shelf space in a tightening market. Boys in particular seem to be abandoning traditional toys at earlier ages in favor of consumer electronics, video games, PC software and the Internet. The fact that kids are growing more tech-savvy , a trend called "age compression ", has troubled toy companies for at least a decade. Action figures, for instance, used to be considered healthy for boys up to age 12. Now the items are mainly marketed to boys 4 to 6. A recent study found that... Question: The sales of construction sets are decreasing because . Answer:
OPTIONS:
- they are not healthy toys for children
- they are very weak and easily broken
- they are hard to find on shelves of toy stores
- they are aimed at boys who are easily attracted by the video games
output:
they are aimed at boys who are easily attracted by the video games
