Question

We often go to work ….. the car but we are going … the bus.

Answer 1

1.in the car
2.on the bus

Answer 2

The sentence you provided is incomplete, so I'll offer a couple of possible completions:

1. We often go to work by the car but we are going by the bus.
2. We often go to work in the car but we are going on the bus.

These completions use different prepositions to indicate the mode of transportation. The first completion uses "by" for both the car and the bus, while the second completion uses "in" for the car and "on" for the bus. The choice of preposition may vary depending on regional and stylistic preferences.
