question:
What feature of airports was significantly increased in length to deal with the increase in jet aircraft traffic?, Context: Airport construction boomed during the 1960s with the increase in jet aircraft traffic. Runways were extended out to 3,000 m (9,800 ft). The fields were constructed out of reinforced concrete using a slip-form machine that produces a continual slab with no disruptions along the length. The early 1960s also saw the introduction of jet bridge systems to modern airport terminals, an innovation which eliminated outdoor passenger boarding. These systems became commonplace in the United States by the 1970s.
answer:
Runways


question:
What is the first low value sales item IBM abandoned, Context: IBM has constantly evolved since its inception. Over the past decade, it has steadily shifted its business mix by exiting commoditizing markets such as PCs, hard disk drives and DRAMs and focusing on higher-value, more profitable markets such as business intelligence, data analytics, business continuity, security, cloud computing, virtualization and green solutions, resulting in a higher quality revenue stream and higher profit margins. IBM's operating margin expanded from 16.8% in 2004 to 24.3% in 2013, and net profit margins expanded from 9.0% in 2004 to 16.5% in 2013.
answer:
PCs
