Answer
Brief Explanations:
The passage starts by stating that in March 2016, Death Valley had a "super bloom" of thousands of yellow wildflowers. Then it explains that Death Valley is usually hot and dry (average yearly precipitation is just two inches, making it hard for flowers to grow). But in October 2015, there was more than three inches of rain in some areas (unusually wet season). As a result, dormant wildflower seeds grew, leading to the bloom. The first option only mentions the difficulty of flower - growth due to hot and dry conditions, but the passage is mainly about why the bloom happened (because of the unusual rain). The second option captures the main event (thousands of wildflowers grew in 2016) and the cause (unusual amount of rain).
Answer:
Because of an unusual amount of rain, thousands of wildflowers grew in Death Valley in 2016.
