Question

which is the best way to complete the text? sir william herschel discovered was also the first astronomer to accurately describe the spiral structure of the milky way galaxy. uranus, and, he uranus, and he uranus, in addition, he

Explanation:

• "Uranus, and, he" has an extra comma which is incorrect in standard English grammar.
• "Uranus, in addition, he" is an incorrect construction. "In addition" is usually used in a different sentence structure (e.g., "In addition to discovering Uranus, he...").
• "Uranus, and he" is a correct compound - predicate structure. The first part is "discovered Uranus" and the second part is "was also the first astronomer...". The conjunction "and" correctly connects the two actions of Sir William Herschel.

Answer:

Uranus, and he
