This unit, we have studied coherence -- the flow from one idea to the next -- in writing. Let's practice introducing and recognizing coherence. We looked at four specific ways of improving coherence:

• Transitional words and phrases

Internet users do not always think about how their internet data is being used.Nonetheless, collecting and using data about search habits is big business.

• Repetition of key words and phrases

Companies are able to track the searches made by various demographics and use data about these searches to target advertisements to likely customers. Customers will see advertisements that match their interests, but they have give up some privacy in return.

• Pronoun reference

For some customers,this loss of privacyis acceptable, while others are deeply concerned.

• Parallelism

Customers may worry about their search data getting into the wrong handsor about further intrusion into their private lives.

Obesity is the leading cause of most major illnesses including diabetes. It would make sense that Congress would no longer consider weight-loss medication a "lifestyle" medication. This medication needs to be rigorously evaluated to serve both diseases as there are many medications on the market that have dual purposes. The people deserve to have affordable access to these medications regardless of prejudice to the Medicines purpose. Since over 40 percent of the population suffers from obesity, this could be the solution. Insurance companies are holding out to see if there are going to be any long-term effects from using the drug as weight loss management. The main concern here should not be who can buy it opposed to who needs it.
