Answer:
The answer is ADHD (Attention deficit/hyperactivity disorder).
Explanation:
ADHD is characterised by three symptoms.
- Inattention: the person can't stay focused on a task, and might not pay attention when spoken to directly.
- Impulsivity: they feel a sudden urge to take action, without thinking too much about the long term consequences.
- Hyperactivity: they engage in constant movement such as fidgeting, tapping and making repetitive noises.
It differs from ADD (Attention deficit disorder) because ADHD involves impulsive and restless behaviour.

Answer:
- Explanatory
Explanation:
<u>Explanatory variable</u> is elucidated as the variable that could affect the response variable. This variable is quite identical with the independent variable as it can be controlled or changed that may affect the response variable(which is similar to dependent variable). However, the observational studies observe the natural responses without any manipulation and therefore, these variables cannot be changed always. In the given example, the 'number of hours spent on studying for the test' would be the explanatory variable as it directly influences the response variable i.e. 'grades.'
