Though Homo habilis made blunt cutting tools, Neanderthals
fashioned finer implements, tapering from the butt to the
point and flaked on two sides, to form the familiar teardrop now paradigmatic of early man.
(A) point and flaked on two sides, to form
(B) point, flaked on two sides, and formed
(C) point, flaking on two sides, that form
(D) point, flaking on two sides, forming
(E) point and flaked on two sides, form
I know "tapering..." and "flaked...” are modifiers, but I'm confused whether "fashioned" and "formed" are parallel? Can anyone help? Thx in advance
