Hi, Zafar,
Start with the nouns. Commission and committee mean somewhat the same thing. They're both groups that are set up for a specific reason. A commission is more formal (according to Webster's Dictionary), while a committee is usually more informal. For example, a political body might appoint a commission, while a company or a social group might have people form a committee.
Then think about the adjectives. Commercial means having to do with commerce, or business. What kind(s) of commissions deal with commercial issues? What kind(s) of committees might deal with commercial issues?
Also consider the other meanings of commission and commercial. Commission can mean money that is paid to someone who sells something (like real estate). In that case, a commercial commission would mean that a real-estate agent sells property for business use.
Commit and commitment indicate a promise to fulfill a duty or obligation. Consider those words as part of committee. When people serve on a committe, they promise to fulfill a specific duty or obligation. For example, a fundraising committee promises to raise money for a cause.
Finally, consider the adjective common.This can mean something that's widely used or widely known. In the context of your word list, it might mean a common objective. The commission or committee is committed to a common objective, such as fundraising.
When you understand the meanings of each word, describe the differences and similarities between a commission and a committee. Invent a name for the commission and the committee, and describe the people who serve on them . Are they committed to their purposes and goals? Are they working toward a common objective? Are they working in the commercial realm, or as part of a private group? Naming the individuals will make your story more interesting, while still using the words on your list and showing that you understand them.
