Answer 1

It looks like you need the blanks filled and the fragments cleaned up. Suggested fills:
- "to the French forces"
- "border"

Polished version combining the fragments:
"America was changing, but it took time. The Harlem Hellfighters were turned over to the French forces to fight with the French. Moving into the 21st century, changes came to Texas. The biggest issue today is the crisis at the border. It is dangerous to cross the border, and many have died."

If you want a different tone (more formal, more detailed, or expanded into a paragraph for a paper), say which and I can revise.
