Can someone
increased competition between producers of a good may lead to
a. a decrease in profit
b. an increase in price
c. a drop in demand
d. a rise in taxes

A. a decrease in profit

Explanation:

Increased competition between suppliers of the same product tends to benefit consumers, as competition leads to a decrease in the price and profit margin of suppliers. As more competitors participate in the market, each one tries to sell the product at a lower price to gain a larger share of the market. Consequently, the profit margin is smaller and only the most efficient suppliers tend to remain in the market in the long run.

this null effect is caused by a weak manipulation and ineffective internal validity. in a scientific study, as the one dr. morimoto is trying to perfom, internal validity refers to the confidence placed in the cause-effect relationship and to how well an experiment is done and able to eliminate confounding variables.
