Article Comprehension (C.E Reading) - Questions and Answers

Article Comprehension:

1. What causes cavities?
2. What was the genius idea the scientists at OraganoBalance came up with to try combat cavities?
3. What was the experiment they conducted to test their thesis? Was it successful?

Comprehension Answers:

1. People think that sugar is the main reason you get/have cavities. It is not. It is something in your saliva that feeds of the remains of the sugar (after you have finished digesting the food) and makes the cavities. It is called "streptococci mutants". They (like I said before) feed of the remains of the sugar while sticking to your teeth. While this is happening the spit of acid, this is the cavities.

2. The people of OraganoBalance had an idea that they could use a substance called "Lactobacillus Paracasei". This is a bacteria found (naturally) in milk products. The reason they got this bacteria was so it could bind with the streptococci mutants and this could result in the streptococci mutants getting dragged away from the teeth. It was an idea that seemed good because it was tested on rats (it seemed to work then).

3. The team at OraganoBalance made two batches of mint candy, each of these batches are coated with different dead types of lactobacillus paracasei. The third batch was bacteria free. They each then tested the candies. They found that the tests were successful and they did work.
