Self-study
The same task triggers different levels of awareness of one's surroundings, called environmental awareness, in different individuals. ████████████ ████████ ███ ████████ █████ ████ ██████ ██ ████████ ████ ██ ██████████ ████ ██████████████ ███ █████████ ███ ██████ █████████ █████████ ███ ███████ ██ █████ ██████ ███████████ ██ ██ ███████ ██ ██████ ███ ████████ ██████████ █ ████████ ██ █████████████ █████████ █████ ███████ ███ ███████ █████ ████████ █████████████ █████████ ███ ████ ██████ ███ █████████ ███████ █████ ██████ ███ █████████ █ ████ ██ ███ ███ ██ █████ █████ ██ ███████ ████████
Summary
The same task causes different levels of environmental awareness in different individuals. For example, mathematical puzzles cause most individual’s environmental awareness to increase. Some people experience a decrease in awareness because they solve the puzzle visually in their mind’s eye. Other people may experience an increase of awareness because their brains signal a rest after every stage of problem solving.
Strongly Supported Conclusions
For at least some people, mathematical puzzles do not cause an increase in environmental awareness.

Which one of the following ██ ████ ████████ █████████ ██ ███ ███████████ ██████
a
There are some ██████ ███ ████ ████████████ ███████ ██ ███ █████ ██ ████████ ██ █████ █████ ██ █████████████ ██████████
This answer is strongly supported. We know from the stimulus that some people, those who are visual problem solvers, mathematical puzzles can cause their awareness to decrease.
b
People who visually █████████ ███████ ██████ ████ █████ ███████ ███████ ██ ████ ███ ██████ ███ █████ ██ █████ █████████████
This answer is unsupported. We don’t know anything about other problem solvers from the stimulus to make this comparison.
c
People tend to ██ ████ █████ ██ █████ ████████████ ████ ███████ ████████████ ████████ ████ ████ ███████ ███████████████ █████████
This answer is unsupported. We don’t know what effect non-mathematical puzzles may have on a person’s environmental awareness. The stimulus is limited to the example of mathematical puzzles.
d
Mathematical problem solvers ███ ████ ██ ██████ ██████████ ██████ █████ ██ █████ ████████████ ████ ██████ ███████ ██ █████
This answer is unsupported. To say that these problem solves “only” become aware during periods of rest is too strong. We know that this may be one period, but not the only period.
e
Mathematical problem solving ████████ ████████ ███████ ██ ████ ██ ███ ████ ██ █████████ █████████ ██ ███ ███████ ████████ █████████████
This answer is unsupported. We don’t know from the stimulus what is required for a person to solve mathematical problems.
