What is the cause? ( 12 ) weather and drought (2) conditions in Mexico. It's not (13) chili peppers. Mustard producers in France and Canada said extreme weather caused a 50% reduction in seed production last year, ( 14 ) to a shortage of the condiment on grocery store shelves. Blistering heat, stronger storms, droughts, floods, fires and changes in rainfall (15) are also affecting the cost and availability of staples, including wheat, corn, coffee, apples, chocolate and wine. The climate crisis is increasing the intensity and ( 16 ) of extreme weather events — and it's putting food production at risk. "Almost everything we grow and ( 17 ) in the US is facing some climatic stress," said Carolyn Dimitri, nutrition and food studies professor at NYU. Wheat and other grain crops are particularly ( 18 ). In the Great Plains region, (19) most of the US's wheat is harvested, drought depressed the winter crop.

Food production is a driver of the climate crisis and a (24) of it. ( 25 ) the food system will require a wide variety of actions, including increasing crop diversity, delivering climate (26) to farmers around the world, expanding conservation programs and offering growers insurance that pays out when an index such as rain or wind speed falls above or below a fixed limit. The Biden administration is supporting research into "climate-smart" agriculture, an approach to managing cropland, forest, fisheries and cattle that attempts to address the intersecting challenges of the climate crisis and food ( 27 ). In May, the UN secretary general, António Guterres, said that climate-related disasters and extreme weather were a driver of global hunger and that 1.7 billion people ( 28 ) by the climate crisis over the last decade. Experts say (29) action is taken, we can expect to see increased food prices, decreased availability and conflict over water, which will primarily affect poorer countries and low-income Americans, (30) everything from school lunches to food aid programs. © Copyright Guardian News & Media Ltd 2023 (1) sriracha (2) drought かんばつ 世界中で人気のチリソース

問5で(3)の訳が問われているのですが なぜafter等もないのに4時間"後"と訳せるのですか?

試験本番でのこの本での 目標時間 目標時間 Lesson 4 103 次の英文を読んで、後の問1~5の設問に答えなさい(固有名詞はそのまま使用し てよい)。 5 15 分 分 22 分 ◆解答・解説本冊 p.6 Here's a possible strategy to boost" memory-exercise four hours after you learn something. In a study published in the July 11, 2016, Current Biology, researchers found that exercise after learning may improve your memory of the new information, but only if done in a specific time window *2. (In the study, 72 participants learned 90 picture-location associations mentally linking an image with new information in order to improve recall over a 40-minute period. They were then randomly assigned to one of (1) three groups: one group exercised immediately, the second exercised four hours later, and the third did not exercise. The exercise routine consisted of 35 minutes of interval 10/training on a fitness bike at an intensity of up to 80% of maximum heart rate. After 48 hours, the participants' memory was tested while their brains were scanned*4 via MRI*5. Those who exercised four hours after the learning session retained*6 information better than the other two groups. The MRI also showed the hippocampus, the brain region involved with learning and memory, - that (2) 15 was more active when information was recalled correctly. Newly learned information turns into long-term knowledge through a process that requires certain brain chemicals that are released during exercise, but more research is needed to understand (3) this phenomenon. (4) It is also not clear why four hours was more beneficial, or if another time frame might produce a similar 20 effect.
