Read the following passage about coffee and mark the letter A, B, C or D on your answer sheet to indicate the best answer to each of the following questions from 23 to 30.

        Coffee is one of the most widely consumed beverages in the world, enjoyed by millions of people every day. Around the globe, coffee production provides employment for about 25 million farmers and farmworkers and contributes significantly to the economies of many countries. Brazil remains the largest coffee producer, harvesting billions of pounds of coffee each year. Vietnam, Colombia, and Ethiopia are also major producers, exporting millions of tonnes annually. In the United States alone, billions of dollars are spent each year importing coffee, while coffee sales generate even higher profits for businesses.

        Despite its popularity and economic importance, coffee farming faces serious challenges due to climate change. Coffee plants are sensitive to temperature, rainfall, and soil conditions. If the climate becomes too hot or too cold, or if rain is insufficient or excessive, coffee plants may fail to produce beans of good quality. Current regions with ideal conditions for coffee growing may no longer be suitable in the coming decades. For example, in Brazil, some areas that now produce top-quality coffee could become unusable by 2050.

        Climate change also increases the risk of pests and diseases. The coffee berry borer, a beetle that feeds on coffee beans, thrives in warmer climates. Similarly, coffee rust, a disease that causes coffee trees to lose their ability to produce berries, becomes more common when temperatures rise and rainfall becomes irregular. Farmers and scientists are working to develop more resilient coffee varieties and improve farming techniques to counter these threats, but the future of coffee cultivation remains uncertain.

        Coffee continues to be a favorite drink worldwide. Without global action to mitigate climate change, the availability and quality of coffee may decline, affecting millions of people who depend on it for income and enjoyment. Protecting coffee requires collaboration among farmers, governments, and consumers to ensure that this beloved beverage remains part of our daily lives for generations to come.
