Kopi luwak, the most expensive coffee in the world, is made by feeding coffee beans to small mammals called lemurs. These lemurs then excrete the undigested beans, which are collected and processed to make the coffee. Is this true or false?
Answer: False
Kopi luwak, or civet coffee, is made from coffee cherries eaten and defecated by Asian palm civets in Southeast Asia, particularly Indonesia. However, lemurs are endemic to Madagascar.
Civets have been subjected to intensive farming, where cages and battery farming methods, including force feeding, have been used.

Is it true or false that the US Army used camels in the American West during the mid-19th century?
Answer: True
In the 1830s, the US Army struggled with westward expansion due to challenging terrain. In 1855, Secretary of War Jefferson Davis funded an experiment to import camels for military use, led by Major Henry C. Wayne. The expedition brought 33 camels from the Mediterranean to Texas, where they demonstrated superior carrying capacity, speed, and endurance over horses and mules. Despite initial skepticism about their temperament and odour, camels adapted well to the Southwest’s harsh conditions. Although successful, Congress denied further funding, and the Civil War ended the experiment. The camels were sold at auction, eventually being released into the wild.

Is it true or false that sea otters gather and socialise in groups called rafts?
Answer: True
Sea otters, once hunted extensively for their fur, saw their population drop to 1,000–2,000 individuals. Conservation efforts, including an international hunting ban and reintroduction programs, have helped their numbers rebound, allowing them to occupy about two-thirds of their former range. Despite these successes, sea otters remain endangered due to recent regional declines. They often gather in large groups called rafts while resting on their backs.
