question: are Kenneth Clark and Carol Shields both nationals of English speaking countries ?
answer: yes
context: Title: Carol Shields
  Passage: Carol Ann Shields, {'1': ", '2': ", '3': ", '4': "} (née Warner; June 2, 1935 – July 16, 2003) was an American-born Canadian novelist and short story writer.

  Title: Pedro Chamorro
  Passage: The name Chamorro may be both a patronym and a matronym.  In Spanish speaking countries, the patronym is usually followed by the matronym to more precisely identify an individual (See Iberian naming customs).  In English speaking countries, the matronym is frequently omitted, resulting in ambiguity.  Omission of a given second or middle name further obfuscates an individual's identity.
  Title: Kenneth Clark
  Passage: Kenneth Mackenzie Clark, Baron Clark, (13 July 1903 – 21 May 1983) was a British art historian, museum director, and broadcaster.  After running two important art galleries in the 1930s and 1940s, he came to wider public notice on television, presenting a succession of series about the arts during the 1950s and 1960s, culminating in the series "Civilisation" in 1969.
