Решение:

1. Paragraph C: «The Coda, a four-door electric car, was a product ahead of its time. It was manufactured by Chinese automotive company Hafei for China’s domestic market. The company redesigned it, with a better battery than other electric vehicles at the time, to sell on the international market.»
2. Paragraph B: «Microsoft® SPOT, or Smart Personal Object Technology, provided information to electronic devices over FM radio waves at a time when there was no wi-fi or Bluetooth. The first SPOT devices were smartwatches, made by international watch companies such as Fossil® and Swatch®. The SPOT Watch received weather information, news headlines and short messages and, as a unique feature, functioned as an independent, standalone device. But you couldn’t send messages. The product soon disappeared from the market as mobile phones were rapidly becoming smarter and the smartwatch became a smartphone accessory.»
3. Paragraph A: «Samsung’s® Note 7 was marketed as ‘the best phone ever made’, in a race to compete with Apple’s iPhone®. However, Samsung soon recalled its product after dozens of Note 7s exploded. It then got worse. Several replacement phones caught fire and a Southwest Airlines plane was evacuated when a phone began smoking. Five days later, production was discontinued and the company lost billions of dollars.»
4. Paragraph C: «However, the electric car market hadn’t taken off yet. Coda wasn’t financially stable enough to wait for the market to grow and, crucially, the car’s body design did not appeal to consumers.»
5. Paragraph B: «The product soon disappeared from the market as mobile phones were rapidly becoming smarter and the smartwatch became a smartphone accessory. Although it was outcompeted, you can see many of its design features in current watches, so not all was lost.»
6. Paragraph A: «Several replacement phones caught fire and a Southwest Airlines plane was evacuated when a phone began smoking.»
