Answer&Explanation:
A heuristic is our way of using a mental shortcut to make a decision or resolve issues quickly and effecient.
This helps a person not take too much time trying to figure out their next step. They can be useful but they can also lead to cognitive biases.
A) When you want to study for a hard test you are likely to think of what strategies you have used before and whether they have worked so it like you will be using availability heuristic, and if your recall some strategies that have succeeded before you are likely to believe they will also make you successful this time around and then follow those again.
If the strategies you have tried before have never worked you are likely to consider another strategy using what other have done before and have succeeded doing that.
B) if you wnatgto go on a date you are likely to think of what you know about this person
2. Use what you know of them to ask them properly.
