Question

B. READING TO THE TOP OF THE WORLD The coldest walk in the world is probably the one Alan Chambers and Charlie Paton did a few years (14) .. when they walked to the North Pole. To prepare for the trip they (15) ........... a day in a freezer at a temperature of -30°C. But they were more comfortable there than at the North Pole (16). they weren't tired or hungry! at the North Pole 70 days 8 March 2000 and (18) during the trip and he was amazed when Alan gave him (20) They began their 1,126 km walk (17). later. A plane took them straight home from there. Charlie had his 30th (19) small cake with a candle on it. Alan said the (21) that cake. The strange thing is that more men (23) moment for him was Charlie's face when he (22) walked on the moon than to the North Pole.​

Answer 1

Exploration of the coldest regions on Earth, including the North Pole and Antarctica, reveals extreme temperatures where Antarctica holds the record for the lowest temperature recorded on Earth's surface. Laboratory experiments have reached even colder temperatures, while the coldest known place in the universe is the Boomerang Nebula.

Step-by-step explanation:

The exploration of polar regions and their extreme temperatures has been a significant challenge for human endeavors over centuries. The coldest regions on Earth, such as Antarctica, have seen temperatures plummeting to record lows of -128 °F (-89 °C) at research stations.

In contrast, laboratory experiments have achieved temperatures far colder, reaching as low as 1.0 × 10-10 K at the Helsinki University of Technology in Finland. Still, these pale in comparison to the natural cold of the Boomerang Nebula, the coldest known place in the universe outside a lab, with a temperature of 1 K.

Early explorers like Fridtjof Nansen embarked on perilous journeys to conquer the North Pole, while Norwegian, Viking sagas recount settlers discovering regions with remarkably temperate climates for their high latitudes. Antarctica remains humanity's key frontier for studying extreme cold, where research stations are the only permanent human presence due to the continent's incredibly low temperatures, even in summer.
