All of these statements about labor unions are true except: unions tried to represent all workers, no matter their race, gender, or ethnic background

unions usually represented workers in a single industry, such as railroad workers

unions worked in order to advance the common interests of their members

when a country suffers, for example, a drought period, the market product is affected for a low offer, in this case, potatoes; the government has to tax to the households, which have to give more money for the potatoes which they consume, that situation make them consume substitute goods even through loans, it could increase the financial market movement and the inflationary phenomena, the business has to increase salaries in order to the employees could buy a more expensive food (potatoes) and in order to inflation tha business had to buy expensive supplies in the factor market, while the rest of the world have to gain more money to consume the same amount of potatoes.

you really can't answer this on your own?
