Question

climate naturally change over time, and desert organisms have evolved along with these changes. however, recently the climate has been changing too fast for plants and animals to keep up. global temperatures continue to rise, and desert temperatures are rising even faster. as the deserts heat up, they are expanding. every year, over 60,000 square miles of grass and farmland are turning into desert. this process is called desertification. over time, many plant and animal species could become extinct. losing farmable land to desert also means there may not be enough land for humans to grow food. it is important to find ways to combat desertification to ensure survival.
based on the passage, which of these is true?
choose one option
a climate change is contributing to desertification.
b desertification affects humans as well as plants and animals.
c desertification could cause the loss of biodiversity, the diversity of species.
d all of the above

Explanation:

• Option A: The passage mentions that as global temperatures rise (climate change aspect), deserts are expanding (desertification). So climate change is contributing to desertification.
• Option B: It states that many plant and animal species could become extinct (affects them) and there may not be enough land for humans to grow food (affects humans).
• Option C: With many plant and animal species facing extinction due to desertification, it implies a loss of biodiversity.

Since all options A, B, and C are supported by the passage.

Answer:

D. all of the above
