Read the passage and answer the questions that follow.
In the 19th century a series of discoveries were made across Europe, in Belgium, Gibraltar, Germany and Croatia. Interestingly, it was the site of the third discovery that lends its name to what was found. Named after the Neander valley in Germany, scientists had uncovered the first evidence of Neanderthal man. Since then, their remains have been found across Western and Central Europe, in the Levant and in regions of Northern and Western Asia. No remains have been found in Africa to date. At their peak, it is thought that the population of Neanderthals may have reached 70,000.
Today, Neanderthals are classed as a species or subspecies of human. They are closely related to us and share 99.7% of our DNA. We also lived alongside each other in Europe for a few thousand years. However, they became extinct about 40,000 years ago, and modern humans did not. There are a number of theories that seek to explain why the Neanderthals disappeared, but we cannot be certain of the exact reason. One scenario assumes that Neanderthals and modern humans were separate species and the arrival of humans, together with climate change, meant that they were gradually replaced.
Some argue that this interaction between the two species may have been violent. Another scenario places Neanderthals as a subspecies of human that interbred with us and disappeared through being absorbed into the population. The exact nature of the relationship between Neanderthals and modern humans has not been scientifically proven and is contentious. There are also extinction theories that put the blame on an extreme volcanic event. We do know that about 55,000 years ago the climate started to fluctuate between extreme cold and milder conditions. Rapid fluctuations, occurring within a few decades, may have made it difficult for Neanderthals to adapt and survive.

What is the significance of the discovery in Germany?

ANeanderthals were named after a place there.
BNeanderthals became extinct there.
CThey reached 70,000 mark in Germany.
DIt was the first time Neanderthals were discovered outside Gibraltar.

Read the passage and answer the questions that follow.
The current 'biggest' threat to climbers on the world's tallest peak, the former head of the Nepal Mountaineering Association said, is the staggering amount of human waste being left on its slopes with some estimates putting that number at more than 8,500 kilos for this season alone.
The biggest problem and concern now on Everest is human. It is impossible to know exactly how much litter is spread across Everest because it only becomes visible when the snow melts. But at Camp 2, two levels higher than Base Camp, Sherpas who worked on the government's cleanup drive this spring believe around 8,500 kilos of human waste was left there during this year's climbing season. The clean-up took 3 weeks, and the Sherpas were continually going up and down the mountain with sacks.
Melting conditions at Camp 2 create an odour that is sickening to climbers, and the waste will eventually contaminate water sources below and become a health hazard, Tshering warns. "During our expedition to Camp 2, eight of our 10 Sherpas got stomach illness from bad water at Camp 2," said John All, a professor of environmental science at Western Washington University who visited Everest on a research expedition.
Ang Dorjee, who heads the independent Everest Pollution Control Committee, has demanded that the Nepal government institute some rules. The problem is there are no regulations on how to dispose of the human waste. Some climbers use biodegradable bags that have enzymes, which decompose human waste but most of them don't.
Instead of using the makeshift toilets, many climbers dig a hole in the snow, letting the waste fall into small crevasses. However, rising temperatures have thinned the glacier, leaving fewer and smaller crevasses. The overflowing waste then spills downhill towards Base Camp and even communities below the mountain.
Local people living at the Base Camp use melted snow for drinking water -- and for them, the human excrement poses a health risk. Tshering and other mountaineers say the government should mandate the use of biodegradable bags for human waste. The bags are expensive and have to be imported from the United States.
