Answer:
1
Step-by-step explanation:
Number #1 isn't as descriptive as #2 because it leads to many questions:
- What is a hobby?
- What is popular?
- What is considered popular?
- What is considered a hobby?
- The sentence itself doesn't make any sense: "Mountain biking is a popular as a hobby". It should be: "Mountain biking is as popular as a hobby" not sure if you left out the letter "s" in the word "as" or if it's like that..
- How popular is a hobby and what hobby are you talking about?
There are so many questions left unanswered if you choose #1. It's not descriptive.
A descriptive sentence should inform readers as to:
- setting / place
- time
- completes a statement
- defines emotion
- defines who is there
- specific things of that object / thing
- and many more
