You are a critic scoring expert, and you will be given a question-answer pair.  Your task is to score the answers according to the following requirements：

a. You are encouraged to give points critically and identify the shortcomings of the problem and give a score.
b. You should rate the answer on 3 aspects:
1. accuracy: whether the answer correctly answers the question.
2. coherence: assess the structure and logic of the answer
3. comprehensive: determine if the answer covers multiple aspects of the question and provides a comprehensive response. 
**Each for 1 point.**
c. Return form like Accuracy: 0 coherence:1 comprehensive:0 (score only can be 1 or 0)
d. Please make sure you read and understand these instructions carefully. Please keep this document open while reviewing, and refer to it as needed.

Question:  What is the nature of dark matter and dark energy, and how do they impact the formation and evolution of galaxies?
Answer: Dark matter and dark energy are two mysterious substances that make up the vast majority of the universe. Dark matter makes up about 27% of the universe, while dark energy makes up about 68%. The remaining 5% is made up of ordinary matter, which is the matter that we can see and interact with.\n\nDark matter is invisible, but we know it exists because of its gravitational effects. For example, galaxies rotate much faster than they should be able to if they were only made up of visible matter. This suggests that there is a lot of invisible matter in galaxies that is providing extra gravity.\n\nDark energy is even more mysterious than dark matter. We know it exists because of its effect on the expansion of the universe. The universe is expanding, and it is expanding at an accelerating rate. This acceleration is thought to be caused by dark energy.\n\nDark matter and dark energy play a major role in the formation and evolution of galaxies. Dark matter helps to hold galaxies together, and dark energy helps to push galaxies apart. This delicate balance between gravity and expansion is what has allowed galaxies to form and evolve over time.\n\nThere are many theories about what dark matter and dark energy are made of. Some scientists believe that dark matter is made up of weakly interacting massive particles (WIMPs), while others believe that it is made up of axions or sterile neutrinos. There is no consensus on what dark energy is made of, but some scientists believe that it is a cosmological constant, which is a constant energy density that permeates all of space.
