阅读下列短文，从每题所给的A、B、C和D四个选项中，选出最佳选项，并在答题卡上将该项涂黑。
A
A recon study suggests that small shopping shifts can make a difference on green house gas emissions while improving your health. After analyzing the grocery purchases of more than 57,000 households, researchers found 71 percent could reduce their food carbon footprint by following three tips:
Skip the unhealthy snacks
Avoiding foods with high calorie counts and low nutritional value can reduce the total carbon footprint of household food consumption by nearly 10 percent. Items like candy, soda, and packaged snacks take more ingredients and more processing, which translates to higher environmental impacts.
Watch bulk buys
Households of one or two people may end up with food waste when they try to save money with bulk buys. Before you buy supersize, consider whether a three-pound jar of peanut butter will go bad before it’s used up.
Trim ready-made foods
One average microwave meal may not have a very large carbon footprint. But buying them regularly can add up to significant emissions because ready-made foods’ large sales volume increases their carbon emissions, the study found.
By taking the above measures, we could cut more than a quarter of emissions from household food consumption, the researchers say. Collective action can make a huge impact.
