## Why these answers are right

**14. iv.** Paragraph A introduces the T30 tower, raised in just 360 hours, and says Broad is selling the world's first standardized skyscraper. That stress on something unique fits heading iv, A building like no other.

**15. viii.** Paragraph B follows the modules step by step: they are made at two factories in Hunan, carried by truck, then lifted by crane on site and bolted together. This journey matches heading viii, From factory to building site.

**16. ii.** Paragraph C moves away from skyscrapers to Broad's earlier products, first non-pressurized boilers and then gas-powered air-conditioning units now used in more than 70 countries. These other technical successes fit heading ii, Other engineering achievements.
