A) gunpowder was the invention
Answer:
The correct option is;
1955 to 1970
Explanation:
In the two decades after 1950 the marine and inland fisheries growth rate was 6 % per year reaching 56 million tonnes in 1969 from 18 million tonnes in 1950. There was a reduction in growth rate to 2 million tonnes to 2 % per annum reducing further to about 0 % in the 1990s.
The above trend is consistent with most world's fishing areas, as they reached their captured fisheries production maximum potential.
On the other hand, aquaculture production growth rate has increased from 5% per annum between 1950 to 1969 to 10% per annum in 1990 forward.
Vehicles. We can't do most of the stuff we do now without them. Like, we need dump trucks to carry heavy, heavy loads of garbage to one place. Or like a semi-truck, which helps us move big objects at once without having to walk to the place to drop it off. Trains, planes, buggies, cement haulers, tractor trailers, all of those things are as important as breathing anymore. And telephones; telephones have been used for ages, to help us contact people that are far away, like out of the country. And silverware and plates; people use those all the time! They stop most food accidents, and they can be used to show off their cool designs to other people!
