I. Read the given text carefully and answer the questions from 1-5:
The oddly shaped and upright-swimming seahorse seems an unlikely fish. Yet more than 45 species live in coastal waters around the globe. Scientists have learned their basic biology, but much remains unknown about these charismatic animals.
Preferring calm, shallow waters, seahorses thrive in seagrass beds, mangroves, estuaries, and coral reefs in temperate and tropical waters around the world. Relatively inept swimmers, the fish get around with frantic beats (up to 70 times per second) of a dorsal (back) fin and rely on tiny pectoral fins for stability and steering. Easily exhausted, many are swept away in heavy currents or killed in storm-roiled seas.
Seahorses are ambush predators: They hold still and wait for krill, copepods, fish larvae, and other tiny edibles to float by and then nab them with remarkable speed. Toothless and lacking a stomach for food storage, the animals use their long snouts like vacuum cleaners to suck up plankton nearly continually.
The seahorse is a very unusual animal. Sure, it's a fish, but it's also so un-fish-like. Along with its horse-shaped head, it has eyes like a chameleon that can move independently and a prehensile tail that, similar to a hand, can grip objects. As our understanding of these unique creatures grows, the data is making us realise that seahorses need our help.

II. Read the given text carefully and answer the questions from 6-10:
Detroit is the first public place in the US where you can drive an electric vehicle and it doesn't drain the battery – it charges it.
The quarter-mile (400m) section of road through the Corktown area of Detroit is a pilot of a wireless technology that is capable of charging vehicles as they drive over it.
Electromagnetic coils were laid under the surface and connected to the city's power grid. These create an electromagnetic field just above the road that transfers energy to a receiver attached to a vehicle battery through a process known as "inductive charging". It is similar to the technology used in wireless charging for mobile phones.
The hope is that roads like these may help to combat one of the major barriers that keep people from switching to electric vehicles – range anxiety. With charging infrastructure still not at the levels needed to support large numbers of electric vehicles, and the time it takes to charge a vehicle while on long journeys, most motorists are hesitant about swapping their fossil-fuel-powered cars.
But driving along a road where the car gains some additional charge as it travels could help to extend the range of electric vehicles or even do away with the need for plug-in charging altogether.
Where once mobile phones needed charging cables but can now do without, soon the same may also be true of electric vehicles, says Stefan Tongur, vice president of business development at Electron.
"The evolution of charging will be going from cord to wireless," he told the BBC when we caught up with him at the Consumer Electronics Show in Las Vegas earlier this month. "And we will have roads that can charge vehicles while they drive – and where they park."
