In a recent study conducted at MIT, scientists discovered that the neurological pathways of the human brain are much more complicated than they were previously believed to be and that it will take several more years of study to identify exactly what governs the functioning of the cerebral cortex.
A. In a recent study conducted at MIT, scientists discovered that the neurological pathways of the human brain are much more complicated than they were previously believed to be
The meaning is perfect therefore let us hang on to it
B. The neurological pathways of the human brain were discovered by scientists to be much more complicated than they were previously believed to be in a recent study conducted at MIT
conducted by whom is not correctly answered hence out
C. Scientists, in a recent study conducted at MIT, discovered the neurological pathways of the human brain that are much more complicated than they were previously believed to be
This gives us a meaning asthough they found some new brains that we were far more complicated which is not the intended meaning
D. Scientists discovered that the neurological pathways of the human brain are much more complicated than they were previously believed to be in a recent study conducted at MIT
Similar reasoning as B
E. In a recent study conducted at MIT, scientists discovered that the neurological pathways of the human brain are much more complicated than they had previously believed
beleived to be better serves the cause
Therefore IMO A
