1 / Circle the correct answers:

As a result of this, the human body is not only being robbed of the nutrients it needs to sustain ⁵(himself / herself / itself), but it is also being exposed to ⁶(dangerous  / useful  / healthy) chemicals that can cause serious harm. And that's the problem. But it doesn't have to be a problem any longer because we have found the ⁷(cause / reason / solution): organic food which is food ⁸(of / from / for) plants and animals that are produced without the use of synthetic fertilizers, artificial pesticides, herbicides, antibiotics, growth hormones, feed additives or genetically modified organisms.
