Explanation:

1. In desert climates, an underground spring - fed area of lush vegetation is called an oasis. Prairies are large, flat grass - lands, chapparal is a type of shrubland, and steppes are grasslands too, none of which are specifically associated with desert springs.
2. Chapparal bushes are most commonly found in mid - latitude Mediterranean regions. Coniferous trees are more common in cooler, northern regions, deciduous trees in temperate regions, and prairie grasses in grassland regions.
3. When fossil fuel exhausts are heated in the atmosphere, they produce smog. Fog is a low - lying cloud formed by water vapor condensation, clouds are formed by water vapor in the atmosphere, and ultraviolet rays are a form of solar radiation, not produced by fossil fuel exhausts.

Answer:

1. C. oasis
2. B. Chapparal bushes
