The table below shows the use of some energy production methods over time.


Type of energy Average energy used annually in the past (in million tons) Average energy used annually at present (in million tons) Average energy most likely to be used annually in the future (in million tons)
Oil 200 4000 300
Gas 100 2500 700
Coal 1000 2500 1500
Wind 0.1 50 2000
Hydropower 0.7 60 150
Tidal power 0.02 50 500

which of the following hypotheses can be tested with experiments? select all that apply

1.) a diet low in sugar reduces the risk for heart disease
2.) coffee increases subject performance on intelligence tests
3.) people that brush their teeth live longer than those who don't brush their teeth
4.) scientists will find a cure for cancer before the year 2020

I know that 4 isn't the answer so I selected the other three and it said I was wrong. isn't a hypotheses something that can be experimented on so can't all of the three have experiments If I'm making sense ​
