Greetings. I'd like to compare "protect" and "safeguard". For this purpose I prepared some examples.
britannica.com:
(1a) Sunscreen helps to protect against sunburn.
(2a) The insurance does not protect against damage caused by earthquakes.
my variants:
(1b) Sunscreen helps to safeguard against sunburn.
(2b) The insurance does not safeguard against damage caused by earthquakes.
Are (1b) & (2b) correct? Thanks.
