The discovery that the brain’s connections can change even during old age ________________ previous beliefs that the basic configuration of the brain is fixed by middle age.
This sentence contrasts a discovery and previous belief.
Discovery - brain's connections can change even during old age.
Previous belief - basic configuration of the brain is fixed by middle age.
So we need a word which will overturn the previous beliefs. The correct word from the choice list is undermined.
