Answer:
Ancient Nubian cultures were sophisticated and cosmopolitan, as the region served as a major trading center for goods from the African interior, Arabian desert, and Mediterranean basin. From sub-Saharan Africa, Nubian communities traded gold, ivory, ebony, and animal pelts.
It was an ideal center for trade because it was along the Nile River and near overland trade routes.

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:
c. actions followed by pleasurable consequences are more likely to occur
Explanation:
The law of effect by Edward Thorndike states that responses that produce a pleasurable consequence in a particular situation are more likely to occur again in that situation, and responses that produce a punishment or pain are less likely to occur again in that situation. This law was made in 1905 and it suggests that actions are based on consequences that might have occurred in the past.
