Đáp án thì các bạn đã đúng. Mình chỉ giải thích xíu. Câu khẳng định có chủ ngữ giả (it / there) thì chủ ngữ giả đứng đầu câu, sau đó đến trợ động từ của thì đó, chỗ này chỉ có thể là won't hoặc will, rồi đến động từ nguyên mẫu (be). Câu này có liên từ (as), do đó phải có 2 vế, vế sau cũng phải có chủ ngữ (cụm danh từ) + trợ động từ + động từ nguyên mẫu.
Như vậy dù không biết nghĩa, bạn cũng sẽ có "there will be _______ as fossil fuel won't be ___________.
Phần còn lại dựa vào nghĩa câu nhé.
