Question: Read the following article and answer the question. Article: Mouth bacteria grow fast in airless conditions. Oxygen rich saliva keeps their numbers down.

Some people's breath turns sour every time they go on a job interview. Saliva flow gradually slows with age, which explains why the elderly have more bad breath trouble than younger people do. Babies, however, who make plenty of saliva and whose mouths contain ly few bacteria have characteristically sweet breath. For most of us, the simple, dry mouth variety of bad breath is easily cured. Eating or drinking starts saliva and sweeps away many of the bacteria. Breakfast often stops morning breath. Those with constant dry mouth find that it helps to keep gum, hard candy, or a bottle of water or juice around. Brushing the teeth wipes out dry mouth bad breath because it clears away many of the offending bacteria. Surprisingly, one thing that rarely works is mouthwash. The liquid can mask bad breath smell with its own smell, but the effect lasts no more than an hour. Some mouthwashes claim to kill the bacteria responsible for bad breath. The trouble is, they don't necessarily reach all offending germs. Most bacteria are well protected from mouthwash under thick layers of mucus . If the mouthwash contains alcohol--as most do--it can worsen the problem by drying out the mouth. Question: Which of the following is mentioned as one of the causes of bad breath? Answer:
OPTIONS:
- Tooth trouble.
- Sulfur rich food.
- Too much exercise.
- Mental pressure.
Answer: Mental pressure.
