## Answer

1. Anyone stuck in a room with a mosquito knows they excel at finding you.
2. These insects can detect the carbon dioxide, or CO2, exhaled in our breath.
3. They are also attracted to sweat, body warmth, and contrasting colors.
4. But until now, scientists haven't known mosquitoes can detect specific colors.

## Explanation

The correct sequence establishes a logical flow: starting with the general observation of mosquito behavior, moving to known sensory triggers, and concluding with a new scientific discovery regarding their vision.

(Sentence 1): The paragraph begins by describing how mosquitoes are adept at finding people, setting the context for their detection abilities. (Sentence 2): It then explains that mosquitoes can detect carbon dioxide (CO₂) in our breath, highlighting a key factor in their ability to locate humans. (Sentence 3): The focus shifts to other factors that attract mosquitoes, such as sweat, body warmth, and contrasting colors. (Sentence 4): It concludes by noting that, until now, scientists were unaware that mosquitoes could specifically detect certain colors.

## Hints

- Start by finding the sentence that introduces the topic of mosquitoes finding humans in a general way.
- Look for pronouns like 'they' to see which sentences must follow the ones that introduce the insects.
