New Ideas Iceland's President Olafur Grimsson is trying to drive carbon dioxide underground to 51 its release into the air. Over the next two years, a team of scientists will try to 52 carbon dioxide-charged water into the rock underground. Scientist theory says this should work. The CO2 will react with the rock to form. a stable mineral that remains in the 53 for millions of years. If the experiment succeeds, Iceland could give the world a new 54 to reduce CO2 emissions. Sigurdur Gislason, a university professor in Iceland, says his country has an 55 over other countries: 'We have enormous amounts of clean 56 and a small society.

Homemakers can also save when they renovate, claiming tax rebates 64 up to $500 simply by fitting their homes with energy-saving insulation. If they.--65-- in solar water heating, the payoff at tax time is equal to 30 percent of the appliance's cost or a maximum of $2,000. 51 A) reduce B) narrow C) interrupt D) interfere
