Tobacco can be used in several ways according to its presentation: inhaled (cigarette, cigar, straw cigarette); snuff; chewed (coil smoke), but in all its forms it is harmful to health. The toxic substances act on the most diverse systems and organs, contain more than 60 carcinogens.
Smoking causes about 50 different diseases, mainly cardiovascular diseases such as hypertension, heart attack, angina, and stroke. It is responsible for many deaths from lung, mouth, larynx, esophagus, stomach, pancreas, kidney and bladder cancer and obstructive respiratory diseases such as chronic bronchitis and pulmonary emphysema. Tobacco lowers the body's defenses and thus the smoker tends to increase the incidence of acquiring diseases such as influenza and tuberculosis. Tobacco also causes sexual impotence.
The correct answer is A.
The sentence should be written like this: <span>Sadly, even after that water is found, only some of it's clean and safe enough to drink.
Because the sentence is saying "only some of IT IS clean and safe enough to drink," an apostrophe should be used.
</span>
In the first sentence, the "he" is a nominative as it is a subject.
In the second sentence it is an object as the form "me" is actually "I", but "i" is a nominative form and "me" is an objective form.
In the third sentence "Us" is also used in objective form as "us" is an object of an action by "my sister".
Your paragraph is perfect except that you should not capitalize the word "mythology".
