(33) _____ scientists are now preparing advanced computer technology that will be able to “read” our brains, for the present, tests are still the most popular ways of measuring intelligence. A person’s IQ is their intelligence (34) _____is measured by a special test. The most common IQ tests are run by Mensa, an organization that was founded in England in 1946. By 1976 it had 1,300 members in Britain. Today there are 44,000 Britain and 100,000 worldwide, (35) _____ in the US.

You may be shown photos, drawings, diagrams, maps, plans, advertisements or computer graphics and it is (32)__ that you study them carefully. If necessary, check you know exactly what to do by politely asking the examiner to (33)__ the instruction or make them clearer.
