سؤال إنجليزي للصف العاشر في القراءة والاستيعاب

Butter tea, called po cha, is a popular drink in the Himalayas. The high altitude means that people burn many more calories and the tea is a good source of energy. Locals drink up to 60 small cups every day. It is made from black tea, yak butter and salt and has a flavour that is more like a soup than a tea.
