Explanation:
Aggregate demand spending is composed of four components: consumption (C), investment (I), government (G), and the difference of a country's exports and imports (X − M). If a tax cut occurs, this increases C, leading to a rightward shift of the aggregate demand curve. Long‑run aggregate supply and short‑run aggregate supply will not be affected.
An economy is in equilibrium when AD=AS=LRAS.In this economy AS=AS but is not equal to LRAS. When government increases it's spending the aggregate demand rises because government spending is a part of AD, so AD will shift to the right.
Answer: They provide C subsidies
Concrete operational stage is the correct answer.
Jean Piaget was a phychologist very well-known for his contributions to the child development studies. According to him, there are four stages of cognitive development, the concrete operational stage is one of them. During the third stage, also known as concrete operational stage, 8-11 year olds develop cognitively by using logic that is based on concrete evidence. However, even though these kids are able to learn to retrace their thoughts, correct themselves and see more than one dimension to a problem, most of them still struggle handling abstract concepts.
