D. descriptive investigations
Explanation:
A scientist studying the star Alpha Centauri would probably rely on descriptive investigation to gather data.
In descriptive investigation, experiments cannot be performed since the subjects cannot easily be manipulated or they are far too inaccessible. This form of investigation is based on indirect qualitative investigation of a phenomenon.
- Alpha Centauri is a distant star several light years away from the vicinity of the scientist.
- The best way to investigate this distance body is to make inferences from the evidence gathered from observatory stations using telescopes.
- Astronomers can collect different information and give vivid description of the distant start.
- It is highly impossible to make comparisons and alter variable in this kind of investigation.

Answer: The shape of the skull and the supraorbital height tell us the following about each species-
- It can tell us about the intelligence of species and what all senses they were dependent upon for their survival
- Most of the species possess similar skulls as mostly their structures are oval shaped, sloped or round shaped.
- Species have different food habits that is determined by the teeth, which vary from long and dull to short and dull.
- Variation in teeth and face shapes could also be due to different geological locations.
- In particular, the foramen magnum be located where the spine connects can be attributed to how the species gathered food through hunting and what kind of food they sought after.
- Overall, the shape and the supraorbital height of each skull informs us the advantages and disadvantages each species had in its ecosystem.
- It also tells what probable causes of death would be when the species died.
