Read the passage and answer the questions.
Listening & speaking
Of all the workings of the human body, there is one organ that produces the most intrigue amongst scientists. The brain is the centre of the nervous system and controls most of the body’s activities. Interestingly, it is the back part of the brain that is involved with our vision. The sides of the brain are involved in memory, speech and rhythm.

Read the passage and answer the questions.
Listening & speaking
Although the brain amounts to only about 2% of total body weight, it uses up to 20% of the body’s energy — more than any other organ. Scientists have been conducting research in order to seek greater understanding of the brain, especially since the 1950s. Nevertheless, there is still a long way to go before we can completely understand the workings of this complex organ.
