3 questions: 1. A good mood may put a spring in your step. What's the meaning of "spring" here? 2. Each year more than 1.1. million abortions are performed in the U.S. Nailing down clear safety data has been difficult, because many women must travel and are lost to follow-up tracking. California is one of 17 states that covers abortion and subsequent care for women enrolled in Medicaid. Which means there’s solid data about the procedure in that populous state. And a study that took advantage of the existence of that data found that major complications, or those that required hospital admission, surgery or blood transfusion, are exceedingly rare. They occur in only 1 of 436 abortions. The study tracked some 50,000 women for the six weeks following the procedure, regardless of trimester. The results appear in the journal Obstetrics & Gynecology. What's the meaning of "admission" here? What is "trimester"? 3. What's the difference between "medication" and "medicine"?
