(e) the percentage of people suffering from hay fever who also have asthma is lower than 95 percent.

The correct answer is the D

Explanation:

They do not tell us the population number, we only know that if we join the two groups of patients, it equals 95 percent of each group, therefore the rest of the population would be lower than those with both diseases.

no, because those are both different running competitions. while distance runners train their legs and their lungs to run long amounts of time, the sprinters are training their legs and their lungs to give all they have in the little amount of area they need to cover. the brain also plays a huge part in all of this.

the brain is the only thing in your body that sends messages to your body telling you to run. if you are a long distance runner and you have the mind set of a sprinter, you will not get anywhere. if you have a long distance mind set and you have to run 200m in 20 seconds then you will not make it in time.
