Answer:

a. sham lesion control group.

Where did the british empire expand to and why did they choose these places?
lutik1710 [3]

Answer:

The British Empire was composed of the dominions, colonies, protectorates, mandates, and other territories ruled or administered by the United Kingdom and its predecessor states. It began with the overseas possessions and trading posts established by England between the late 16th and early 18th centuries. At its height it was the largest empire in history and, for over a century, was the foremost global power.[1] By 1913 the British Empire held sway over 412 million people, 23 per cent of the world population at the time,[2] and by 1920 it covered 35,500,000 km2 (13,700,000 sq mi),[3] 24 percent of the Earth's total land area. As a result, its constitutional, legal, linguistic, and cultural legacy is widespread. At the peak of its power, it was described as "the empire on which the sun never sets", as the sun was always shining on at least one of its territories.[4]
