Question

Directions (51–65): Record your answers in the spaces provided in your answer booklet. Some questions

may require the use of the 2011 Edition Reference Tables for Physical Setting/Earth Science.
Base your answers to questions 51 through 53 on the data table below and on your knowledge of Earth
science. The data table lists four constellations in which star clusters are seen from Earth. A star cluster is a group of stars near each other in space. Stars in the same cluster move at the same velocity. The length of the arrows in the table represents the amount of redshift of two wavelengths of visible light emitted by these star clusters.
Identify the name of the nuclear process that is primarily responsible for producing energy in stars.

Answer 1

After studying the table graph you provided in the question and my own personal knowledge of the subject, the name of the nuclear process that is primarily responsible for producing energy in the stars is called fusion or you can use nuclear fusion for the answer. Either will work for the answer.
