Reading the passage
Read the whole relationship: without mass, matter cannot exert gravitational force; without that force, it cannot make other matter cohere. The missing effect is matter coming together into the structures we have been trying to explain. I would predict something like forming or holding together those structures.
Working the answers
- A
Exerting the force is the cause being discussed. Cohere describes what the force makes other matter do. Replacing the effect with exerting gravitational force loses that distinction.
- BCorrect
The opening asks how galaxies and clusters of galaxies form their observed structures. The phrase “form galactic structures” supplies the relevant meaning of coming together here.
- C
Oscillation is a neutrino changing type. Cohere concerns the arrangement of matter under gravity, not that change of type.
- D
Coming together into a structure isn't the same as each particle becoming more massive.
- E
The sentence is not about making new particles through fusion. It is about gravitational force organizing matter into larger structures.
