Article: New Zealand has long been mountain hike mad. Over the last 25 years an increasing number of dedicated cycle tracks and parks have sprung up in both town and country, many developed by bike clubs and other community groups. Recreational cycling was already on a roll, when in 2009 a 50 million New Zealand dollar government fund was established to create a continuous touring route running the length of the country, supported al a grass roots level by an additional 50 million New Zealand dollars offered up by councils and focal organizations. It soon became apparent, however, that building one continuous route across the two islands was not only too ambitious, hut it also would bypass many of the most remote and interesting corners of the country. Restoring and extending historic pathways made more sense, enabling cyclists to visit fascinating historic and cultural sites while seeing natural wonders along the way, and inspiring both locals and people from overseas to ride them. The first sod of the new trails was turned by Prime Minister John Key in late 2(X)9. Since then, armed will machetes, shovels and diggers, some of the world's hest single-track designers and builders have bush-bashed, benched. sidled and switch-hacked their way through a diverse range of terrain . By the encl of 2012, 10 0f the 20 trails were open to riders, with the remainder scheduled for completion by the end of 2,013.The 2,340 km network will be even further extended by already-established trails, such as the famous 71 km Queen Charlotte Track that goes through the Marlborough Sounds al the top of the South Island. Question: Restoring and extending historic pathways would _ . Yes or no, is the answer "allow cyclists to enjoy local history and culture"?
Yes

Article: At night, bats fly through the air, catching hundreds of insects and other small animals. But during the day, they hardly move at all. Instead, bats pass the time hanging upside down from a secret spot. There are a couple of reasons why bats rest this way. First of all, it puts them in a position for takeoff. Unlike birds, bats can't fly into the air from the ground. Their wings don't produce enough lift to take off from a dead stop, and their hind legs are so small and underdeveloped that they can't run to build up the necessary takeoff speed. Instead, they use their front claws to climb to a high spot, and then fall into flight. During the hours when most enemies are active, bats gather where few animals would think to look and most can't reach. This allows them to disappear from the world until night comes again. There's also little competition for these resting spots, as other flying animals don't have the ability to hang upside down. Bats have a unique physiological adaptation that lets them hang around this way without using any energy. For you to hold your fist around an object tight, you contract several muscles in your arm, which are connected to your fingers by tendons ;as one muscle contracts, it pulls a tendon, which pulls one of your fingers closed. A bat's talons close in the same way, except that their tendons are connected only to the upper body, not to a muscle. To hang upside down, a bat pulls its claws open with other muscles. To get the talons to take hold of the surface, the bat simply lets its body relax. The weight of the upper body pulls down on the tendons connected to the talons, causing them to hold tight. Therefore, the bat doesn't have to do anything to hang upside down. Question: What is the passage mainly about? Yes or no, is the answer "How and why bats hang upside down."?
No
