Multiple Choice
The figure below shows the current measurements of the abundances of various light elements in the universe (vertical yellow bar) , along with theoretical predictions. If you redetermined the abundance of ordinary helium (4He) and it was 90% of the current value, what would you conclude about the density of normal matter in today's universe? 
A) It would be higher, and all the various density indicators would agree.
B) It would be higher, but the various density indicators would disagree.
C) It would be lower, but the various density indicators would disagree about its value.
D) It would be lower, but the various density indicators would agree.
E) It would be about the same as current observations suggest.
