Writing Feedback / US government research expenditure- IELTS WRITTING TASK 1 [4]

Energy, and Other over 28 ye other fields would be more appropriate.
"government spending", a little bit of unnecessary usage of capital letter.
The rest looks neat to me. Cheers.

Writing Feedback / IELTS task 2: Humanitarian aid for poor countries in time of natural disaster [3]

Well written, good job by including an apt example.
