Answer: D. Workplace exposure
The workplace exposure is a primary risk factor for developing cancer. Chemical workers, X-ray technicians, ionizing radiation researchers and asbestos workers are those people who work and are exposed to cancer-causing agents. They must follow all safety precautions and as much as possible, minimize any exposure to such compounds.
A dog taking an excessive amount of chocolate would give negative effects such as vomiting, diarrhea, and seizures. This is caused by the caffeine which intoxicates the dog.
50 chocolates would literally KILL the poor dog.
Give the baby something to do and watch her. Do no let her put sand in her mouth if she does and you don’t do anything then she will think that is ok. Therefore she will do it again. So I suggest watching her but giving her something to do.
Example: go get your feet went and take the baby girl with you to get her toes wet too.
Give her a toy to play with. Play with her.
Etc.
I hope this helps!
