Complete question: the complete question is in the attached file below.

1.) The ANGULAR RESOLUTION of the Hubble Space Telescope is better for shorter (bluer) wavelengths of light than for longer (redder) wavelengths of light.

2.) The large research observatories on Mauna Kea use giant REFLECTING TELESCOPES.

3.) SPECTROGRAPHS separate the various colors of light, allowing astronomers to determine stellar composition and may other stellar properties.

4.) The twin 10-m Keck telescopes can work together to obtain better angular resolution through a technique known as INTERFEROMETRY.

5.)The Chandra X-Ray observatory focuses X rays with GRAZING INCIDENCE mirrors.

grazing incidence.

6.) A 10-meter telescope has a larger LIGHT-COLLECTING AREA than a 4-meter telescope.

7.) Galileo's telescope designs using lenses were examples of REFRACTING TELESCOPES.

i think the answer is a, hope this is right, that would be my best guess.
