Answer:
Both shook Japanese confidence and increased US morale.
Step-by-step explanation:
The Doolittle raid occurred in April 1942 where United States Airforce team attacked the Japanese Army. It led to about 50 Japanese soldiers' death with over 400 injured including civilians.
Similarly, the Battle of the Coral Sea involving the United States airforce team against Japanese naval force occurred early in May 1942, and it resulted in about 966 Japanese soldiers' death.
Both outcomes of the encounter help turn the tide of World War II as it "shook Japanese confidence and increased US morale."
