Explanation:

The longitudinal fissure can be define as the deep groove that separates the two hemispheres of the brain of the vertebrates. It is important for conducting neurosurgery as it allows easy splitting of brain into two halves.  A neurosurgeon basically separates the two halves of the brain by pulling them apart using tools.

hope this .!

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this
