Final answer:
The claim about the destructive 1970 typhoon in Bangladesh, coinciding with high tides and claiming about 400,000 lives, is true. Bangladesh is prone to flooding and has experienced several deadly typhoons and cyclones.
Step-by-step explanation:
The statement about the typhoon that hit Bangladesh in November 1970 is True. During the high tides of a full moon, a devastating typhoon hit the region with surges reaching 23 feet and winds up to 155 mph. This catastrophic event led to the tragic death of approximately 400,000 people.
Comparatively, the 1991 cyclone in Bangladesh killed about 150,000 people, while Hurricane Katrina resulted in around 2,000 deaths when it struck New Orleans in 2006. Bangladesh's low elevation and exposure to storm surges make it highly susceptible to flooding, which is further exacerbated by the possibility of rising sea levels due to climate change.
