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, in addition, he uranus, and he

Explanation:

The first part of the sentence states that Sir William Herschel discovered something. Then it continues with another fact about him. The correct way is to separate the discovery (Uranus) from the additional information about him with a comma and use "and he" to connect the two - part statements about Herschel. The first option "Uranus and he" makes it seem like two separate subjects (Uranus and he) which is incorrect. "Uranus, in addition, he" is grammatically incorrect. The correct choice is the one that properly uses a comma to set off the discovery and then connects the two clauses about Herschel with "and he".

Answer:

Uranus, and he
