For answering this question, it is best to try to do the described gestures by yourself in order to visualize them and compare with the given situation. The situation is that choir and orchestra are finishing the song and the volume is decreasing (going down) to the lowest tones. So when we compare all the given gestures with this, we notice that only the third one includes lowering of the hand which represents the lowering of the volume. Gestures often follow the very essence of the action. Some of them are a product of social agreements like clapping at the end of the performance ( Two hands brought together with a clap in front of the chest).
 
        
             
        
        
        
Answer:
Sitting stiffly in front of the steering wheel, I do as my father told me and gently start the car. Carefully I drove it to the middle of the street double-checking, the rearview mirror just in case that a car or a bike suddenly appears. I successfully did the firsts meters without any problems. I made it to the end of my desolated street. Everything was fine, no cars, no kids, no dogs, nothing to worry about.
Suddenly, Tim, that annoying kid with his red ball, sees me from his porch. I saw his face while I was anxiously approaching his ostentatious house, and I knew that he was planning something. Carefully lying my feet on the brakes expecting for him to run in front of the car and my nervous self, I pass in front of his house. I was driving so slowly that I made his target extremely easy. His shiny red ball hit me square in the face making me lose control of the car and hit the brakes just in time before crashing the car against the big oak tree of Mr. Ferguson.

The Romans unified their country with more than just leadership, for they were the inventors of concrete. Concrete, while a boring topic, was the most useful out of all of Rome’s inventions. Concrete is still used today and is why many ancient Roman buildings are still standing even after centuries of withstanding harsh elements. Rome was not stingy with their inventions, shown by the fact that concrete can be seen being used all around the world. Many countries were more than happy to unite with Rome after seeing their inventions and as a result Rome boosted the rest of the world into the renaissance. Rome may have been known for being cruel and brutal in battle, however we as a society must always be greatful for their inventions as we would not be here today without them. 
Also you could talk about how they were the first society to invent democracy, but I didn’t know if you needed inventions or forms of government.

Echolocation used by bats can help them hone in on the tiny noises made by stick insects for a tasty meal.
