Hello Dear Theou,
Welcome!
Please be more careful about what you write. I'm either a learner, but the teachers are very alert to our mistakes here. They even pay a close attention to punctuation and capitalization.
I'm sorry; I don't know your answer, but you can try this:
Could anyone help me with this text? (Don't use "to" after modal verbs.)
I think the right answer is "infrastructure", but I'm not sure. (Use punctuation.)
