MY VOCAB PRACTICE

1. Operate
   It's highly likely that the thieves would operate around this area
2. Cooperation
   I like the cooperation the football team had, the players were all organized and composed
3. Inoperable
   Now I know why the machine was inoperable, after checking it out some vital parts were missing
4. Modus Operandi
   Since we now know the modus operandi of the drone, am sure we operate it better
