All of these statements about labor unions are true
a) unions tried to represent all workers, no matter their race, gender, or ethnic backgrounds
b) unions usually represented workers in a single industry, such as railroad workers
c) unions worked in order to advance the common interests of their members

  A) Unions tried to represent all workers, no matter their race, gender, or ethnic backgrounds.

Explanation:

  Labor unions are organizations that represent workers in many industries. Their activity is centered on collective bargaining over wages, benefits, and working conditions for their memberships. They also represent their members if there is a dispute with management over violations of contract provision.

  Some of the biggest unions in the country engage in lobbying activities and electioneering at the state and federal level.

  They do not represent all workers, they represent their members no matter race, gender, or ethnic. They are divided to represent different industries in order to be more focus on work activity.

the answer as multiple choice is c

africa, the second-largest continent, is bounded by the mediterranean sea, the red sea, the indian ocean, and the atlantic ocean. it is divided in half almost equally by the equator. the continent includes the islands of cape verde, madagascar, mauritius, seychelles, and comoros.

africa’s physical geography, environment and resources, and human geography can be considered separately.

the origin of the name “africa” is greatly disputed by scholars. most believe it stems from words used by the phoenicians, greeks, and romans. important words include the egyptian word afru-ika, meaning “motherland”; the greek word aphrike, meaning “without cold”; and the latin word aprica, meaning “sunny.”

today, africa is home to more countries than any other continent in the world. these countries are: morocco, western sahara (morocco), algeria, tunisia, libya, egypt, sudan, chad, niger, mali, mauritania, senegal, the gambia, guinea-bissau, guinea, sierra leone, liberia, côte d’ivoire, ghana, burkina faso, togo, benin, nigeria, cameroon, central africa republic, equatorial guinea, gabon, congo, democratic republic of the congo, angola, namibia, botswana, south africa, lesotho, swaziland, mozambique, zimbabwe, zambia, malawi, tanzania, rwanda, burundi, uganda, kenya, somalia, ethiopia, djibouti, eritrea and the island countries of cape verde, madagascar, mauritius, seychelles, and comoros.
