Final answer:
The verbs in the correct tense to complete the paragraph about the Kepler mission are 'develop,' 'includes,' 'covers,' and 'enable.'
Step-by-step explanation:
The Kepler mission's goal is to explore planetary systems. To do so, the team must develop a specially designed instrument called the Kepler instrument. The instrument includes a specially designed telescope called a photometer or light meter. It covers a large field of view: 105 square degrees, which is about the area of a hand held at arm's length. Results from the Kepler mission's study enable scientists to understand Earth's place in the solar system.
