Read the following passage about U.S. Regional DAC Hubs: Removing Carbon Directly from the Atmosphere and mark the letter A, B, C or D on your answer sheet to indicate the option that best fits each of the numbered blanks from 18 to 22.

The U.S. Department of Energy's Office of Clean Energy Demonstrations is leading an important program to change Direct Air Capture technology from test projects into working systems. This program focuses on building regional DAC hubs across the country, (18)_________. Unlike normal pollution control methods that stop new emissions, these hubs target old carbon that is already in our atmosphere, offering a way to fix past environmental damage. Each hub must show that it can work in business at large scale; the minimum requirement is capturing one million metric tons of CO₂ every year. (19)_________; it must be permanently stored underground or converted into stable products. These methods make sure the captured carbon stays locked away instead of going back into the air.

The federal government has organized this project through careful steps. Had policymakers waited longer to act on climate technology, removing carbon from the atmosphere would have become much more difficult. (20)_________, providing basic support. The program grew stronger in 2024; more money was given, discussions with experts were held, and extra funding was announced. These actions show real government support; (21)_________. Four domestic hubs are planned, each showing different technical methods for removing carbon from the atmosphere. This varied approach reduces reliance on single methods while creating useful comparison data. It is understood that the final goal goes beyond testing—clear examples (22)_________, with carbon removal abilities expected to be increased to match the size of the climate problem facing present and future generations.
