A. a change in consumer income

C. a change in the cost of raw materials
D. newer technology and improved productivity

Part 2:

The following factors will cause the demand curve to shift:

A. A change in consumer income: If consumer income increases, it will likely lead to an increase in demand for goods and services, causing the demand curve to shift to the right. Conversely, if consumer income decreases, it will lead to a decrease in demand and a shift to the left.

C. A change in the cost of raw materials: If the cost of raw materials increases, it may result in an increase in the price of the final product. This increase in price can lead to a decrease in demand and cause the demand curve to shift to the left. Conversely, a decrease in the cost of raw materials can lead to lower prices and increase demand, shifting the demand curve to the right.

D. Newer technology and improved productivity: If there are technological advancements that improve productivity and lower costs for producers, this can lead to lower prices for consumers. Lower prices can lead to an increase in demand and cause the demand curve to shift to the right.

B. More firms in the market: The entry of more firms in the market can increase competition and provide consumers with more choices. This increased competition can result in lower prices and potentially increase demand, causing the demand curve to shift to the right.

To determine which of the given options will cause the demand curve to shift, let's analyze each option:

A. A change in consumer income: When consumer income increases, people have more money to spend, which typically leads to an increase in demand for most goods and services. Therefore, a change in consumer income will cause the demand curve to shift.

B. More firms in the market: The number of firms in the market does not directly affect the demand for a specific product. It is more relevant to the supply side of the market. Therefore, more firms in the market will not cause the demand curve to shift.

C. A change in the cost of raw materials: Changes in the cost of raw materials can affect the production costs of goods and services. If the cost of raw materials increases, it can lead to an increase in prices, which may result in a decrease in demand. Similarly, if the cost of raw materials decreases, it can lead to lower prices and potentially stimulate demand. Therefore, a change in the cost of raw materials can cause the demand curve to shift.

D. Newer technology and improved productivity: Technological advancements and improved productivity can lead to cost reductions and the ability to produce goods and services more efficiently. This can often lead to lower prices for consumers. Lower prices generally stimulate demand, so this change can cause the demand curve to shift.

In conclusion, options A, C, and D can cause the demand curve to shift, while option B does not have a direct impact on the demand curve.
