Rewrite in plain language

Makes any text clear for a non-expert without losing meaning.

Rewrite the text below so a smart 15-year-old could understand it on the first read.

Rules:
- Keep every fact and number. Do not add new information.
- Short sentences (under 20 words). One idea per sentence.
- Replace jargon with everyday words. If a technical term must stay, explain it in brackets the first time.
- Active voice.
- Keep the original language.

After the rewrite, list any sentence where you were unsure of the original meaning.

Text:
