Answer:
The answer is 3. extinction.
Explanation:
In studies of conditioning, extinction refers to the gradual decrease in responsse to a stimulus. This may occur through habituation, as in the example; or after a prolonged period in which the stimulus has not been present (the person might discover he is no longer afraid of dogs after a long time without seeing or interacting with them).
A response that was believed to be extinct can suddenly reappear. This is called spontaneous recovery.
The correct answer is B. A is wrong because it’s not likely that someone would trade something of high value for something not as great. C is wrong because the barter system is all about exchanging goods for services, and it wasn’t usually an issue. D is wrong because there’s no issue with trading 2 items of similar value.
Answer:
The minimum of bats you can have is 7.
Explanation:
Since the question does not specify if these are different bats or not, we can assume that at least 2 bats can see with both eyes = can see out of their left eye and out of their right eye. We will also assume that there is 1 bat who can see out of his left eye but not his right eye.
Then you'll have the following
2 bats = only see out of their right eye
3 bats = only see out of their left eye
1 bat = Right blinded
We have 3 bats so far.
We can also assume that 4 bats are fully blind.
That leaves us with:
2 bats = good right eye
3 bats = good left eye
5 bats = right blinded
4 bats = left blinded
Trying to rearrange the bats differently will always give out a larger number than 7.
