Gibor Basra and other scientists wanted to find out how weather stars other than the sun have planets orbiting around them. What made this a difficult question to investigate?

The correct answer to this open question is the following.

Although there are no options attached, we can say the following.

What made this a difficult question to investigate is the fact that stars are so far away and other solar systems are even farthest. Although powerful countries have modern technology and modern telescopes, science still has many limits to study space and the galaxy. To answer the question, scientists such as Gibir Basri need deep research and observations to have the correct measurements and come up with valid conclusions.

So in conclusion, it is almost impossible for Basri and other scientists to see planets orbiting faraway stars. Actually, we do not have the technology to do that.
