Answer:
A.) Instead of conquering every island occupied by the Japanese, the military focused on capturing key islands they could use as bases.
Explanation:
The strategy was used to save time and resources so that the American fleet could cover Imperial Japanese territory faster and take advantage of the weak links in the defensive chain.
They also set up bases on conquered islands as staging areas to launch bombing runs against more-defended Japanese island fortifications to pin them down while the US fleet makes closer to Japan.
