19. According to <strong>the</strong> passage, reflective mirrors are 22. The three methods of terra<strong>for</strong>ming mentioned in<br />

difficult to use <strong>for</strong> terra<strong>for</strong>ming because<br />

<strong>the</strong> passage are similar in which of <strong>the</strong> following<br />

(A) it would be impossible to decouple <strong>the</strong> techways?<br />

nology from propulsion systems<br />

They all manufacture greenhouse gasses.<br />

(B) <strong>the</strong>y would create <strong>the</strong> energy equivalent of a<br />

II. They all involve manned missions to Mars.<br />

<strong>the</strong>rmonuclear war, which would delay<br />

III. They all aim to raise <strong>the</strong> surface temperature<br />

colonization of <strong>the</strong> planet <strong>for</strong> centuries<br />

of Mars.<br />

(C) <strong>the</strong>y would melt <strong>the</strong> polar ice caps, <strong>the</strong>reby<br />

flooding <strong>the</strong> planet<br />

launch and position <strong>the</strong>se mirrors have not<br />

yet been developed<br />

without oxygen.<br />

(B) It would take 900 years to grow enough<br />

plants to produce enough oxygen on Mars to<br />

support human life.<br />

(E) relate <strong>the</strong> orbital coordinates of <strong>the</strong> mirrors<br />

orbits at such high speeds.<br />
