What is not a descriptive sentence? 1. Mountain biking is a popular as a hobby.
2. Mountain biking is a nerve wrecking hobby.

1

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

you need to include the text. we have no idea what you are referring to

first one is your answer
