For a few of the largest stars, direct measurements of their disks are possible.

True
False

False

Explanation: Direct measurements of the disks of stars are not possible, especially for the largest stars. Stars, including the largest ones, are far away from us and their disks are too small to be directly observed even with advanced telescopes. Instead, scientists rely on indirect methods such as stellar interferometry and observations of light variations to study the structure and properties of star disks.
