C. Competition
But economics were another cause, but not necessarily poverty
Answer:
Traditional technologies were initially invented during the time when knowledge were still limited. So, their maximum potential were left undiscovered by the people who live in the past.
The efficiency of traditional technologies can be massively improved by adding some key features of modern inventions.
For example, Wheels has existed since 3,500 B.C. But it only reach its maximum potential in terms of speed, durability, and resistance power only after the latest latex and steel technology was invented .
Other example would be light bulbs. It was created in 1879, but only reach it maximum potential in term of energy efficiency after the invention of LED technology.
This is semantic memory.
Semantic memory actually refers to your 'general knowledge' - the information that you know about the world in general. The grandfather's semantic memory is quite strong and it doesn't seem to decline, which is why he is still so good at solving crossword puzzles. This refers to knowledge and memory that we accumulate throughout our lives.
The correct answer is "learning".
The Social Learning Theory is an idea of acquiring information and social conduct, which proposes that new conduct may be acquired through watching and imitating others. It states that getting to know is a cognitive process that takes vicinity in a social context and may arise in basic terms by observation or direct guidance, even inside the absence of motor replica or direct reinforcement.
That would be considered A. explicit memory. Hope this helps!
