Question

question 4
what aided in the confirmation of helium hydride?
more research funding
ultraviolet radiation from aging stars
a cooling universe
improved technology that was tuned to helium hydride

Explanation:

Improved technology allows for more precise detection and confirmation of substances like helium hydride. Research funding may support research but doesn't directly confirm a substance. Ultraviolet radiation from aging stars and a cooling universe are not the main factors in confirming helium - hydride.

Answer:

Improved technology that was tuned to helium hydride
