Which best describes the typical workplaces in Sales and Service careers?

factories, construction sites, offices, and pollution sites
train and bus terminals, warehouses, and shipping and receiving centers
offices and transportation facilities
control towers, warehouses, shipping centers, trucks, trains, and ships

factories, construction sites, offices, and pollution sites

Explanation:

I believe this is right because each of the places in the list is a part of sales and/or service.

Factories- produce product for sale, as well as employing those in the service industry.

Construction sites- These mostly employ service workers.

Offices- These are directly service workers providing products or services.

Pollution sites- Employ workers to maintain the waste.

Hope this helps!  

your word would be isle.

isle is an island or peninsula especially a small one.

if you add the letter "a" you get aisle, which is a passage between 2 rows of something like chairs, shelves, or something else.

ive noticed that too but is this a question
