A. Because you have a repetition on the letter "d"
Answer:
This is
Explanation:
The exciting combination of sight and sound conjures up visions of dragons roaring proudly, breathing fire, and flying through the midnight sky. Determined to find out if dragons really could have existed, I set out on a factual search.
Scientists presented evidence to show why dragons couldn't and did not exist. They said that if dragons had lived, someone would have found remains somewhere in the world.
I noticed that all cultures around the world described dragons in a similar way. I found notes on dragons in old legal documents and in the travel diaries of people like Marco Polo. Dragons are included along with eleven royal animals.
If you create stomach gas like birds do, you could create enough to lift yourself off the ground. If you expel air while diving towards land, it could release gases that could ignite. When the animal died, the stomachs would release strong acids that would dissolve its corpse over time.
Some will believe with all their hearts that legendary creatures roamed our ancient world. I'm not sure which side to believe, but the sound and fury of a night like this make me smile.
Pretty positive its false, don't hate me if I'm wrong, lol.
Answer:the correct verb is appears, the subjects are pigeons and building or science building
Explanation:Why I chose appears is because it makes more sense I don’t really know how to explain it. Why didn’t say several large pigeons together is because several large aren’t really subjects, they’re more like adjectives;describing. I don’t really know about the science building because well it might not be a subject because the pigeons are the main ones and I don’t know if it’s science building or just building because science basically tells what the building is. Hope that helps you.
