Hello experts
for question 3, if we take the first option, absolute age of the galaxy is between 10 to 17 billion years. We can infer that the galaxy was formed during this period of time, and hence this describes the time gap of billion years for the formation of the galaxy.
This is in line with the recent discovery.
However, in E, we are explicitly talking about the stars. The stars are not in question here, but the clusters, which are a group of many stars, are. Hence, if we find discrepancies in the age of stars, there can be other reasons for this as well. What we are interested here is the age of the clusters.
Can you please explain to me where I am getting wrong here ?
