Which sentence has a formal tone? A. I got to visit the Johnson Space Center in Houston, Texas.
B. She was conducting an investigation with a robotic arm.
C. While I was dreaming about being an astronaut, I saw a real live
one at work.
D. There were so many huge spacecraft, and I even got to go in one.

Hello!

B.

Explanation: One by one.

A includes the word "got' which is colloquial, not professional. Instead, they could have said, "I was able to...," or "I accepted an opportunity to...," or something of that nature.

C uses the words "real" and "live" together to create a pragmatic expression that means "genuine" or "tangible." Even so, this is not professional. If one did not know of the social meaning, it would not make sense. In a formal tone, "real live" could be replaced with "un-imaginary," or "real."

D has many grammatical errors and structural inconsistencies. It also has casual words like "huge, "even" and "got." "Spacecraft" should be plural. None of this is formal.

This leaves B, which has no such issues. Formal. Hope that helped.

are you asking for an essay and whats the story?

femininity is conveyed through bernice's personality. she doesn't act how the other girls act and everyone thinks she is weird. she learns how to act in a way that was considered femininely appropriate at the time. she becomes so popular but her attempts to be liked end up backfiring when she is pressured into bobbing her hair. the author wrote that bernice cut off her cousin's hair in revenge for tricking her to cut her hair. this was the authors way of trying to change the way feminine is defined and the way women are expected to act.
