Solution: a)

Now temperatures across Europe are soaring yet again, at or near triple digits from Spain to the British Isles and spreading east.

Low-pressure zones tend to draw air toward them. In this case, the low-pressure zone has been steadily drawing air from North Africa toward it and into Europe.

Heat waves in Europe had increased in frequency and intensity over the past four decades, and linked the increase at least in part to changes in the jet stream. The researchers found that many European heat waves occurred when the jet stream had temporarily split in two, leaving an area of weak winds and high-pressure air between the two branches that is conducive to the buildup of extreme heat.

There may be other reasons Europe is seeing more, and more persistent, heat waves, although some of these are the subject of debate among scientists.

Warming in the Arctic, which is occurring much faster than other parts of the world, may play a role. As the Arctic warms at a faster rate, the temperature differential between it and the equator decreases. This leads to a decrease in summertime winds, which has the effect of making weather systems linger for longer.

Solution: b)

A non-fungible token (NFT) is a non-interchangeable unit of data stored on a blockchain, a form of digital ledger, that can be sold and traded. Types of NFT data units may be associated with digital files such as photos, videos, and audio. Because each token is uniquely identifiable, NFTs differ from blockchain cryptocurrencies, such as Bitcoin.

NFTs have drawn increasing criticism for the energy cost and carbon footprint associated with validating blockchain transactions.

Anything that can be converted into a digital form can be an NFT. Everything from your drawings, photos, videos, GIF, music, in-game items, selfies, and even a tweet can be turned into an NFT, which can then be traded online using cryptocurrency.

Solution: c)

The Black Sea is a marginal Mediterranean Sea of the Atlantic Ocean lying between Europe and Asia.

The Dardanelles Strait, a vital transportation bridge between the Black Sea and Mediterranean Sea, is a narrow channel of water that connects the Aegean Sea to the Sea of Marmara.
