I will never forget the day I accompanied Professor Mackey into the apes' facility for the first time. He delighted in introducing me to all their unique simian behaviors. There were several apes who remained quite diffident during our visit, but most went about their normal behavior, and a few even came forward to greet us. One charmer even offered us a piece of food with his prehensile hand. The professor pointed out the leader, who remained a stolid observer of all the proceedings in the cage. Mackey explained that when the leader did move about, all the apes would become scared and excited and even cower in the corner. Two of the apes fought violently during our visit, but fortunately their rancor seemed focused solely on each other. Undoubtedly, the most fascinating resident was one of the males named Yankee. When the professor closed the cage door after he had brought the apes their lunch, Yankee came to the door and looked for the keyhole. I watched him ruminate there for a few minutes, staring intently at the door and the keys on the bench beside us. He then tried every imaginable way to extricate himself from the cage, and regardless of how impossible it would be without the keys, he seemed resolute enough to continue for hours. Indeed, the professor said he was still trying when he returned later that evening.

The most important thing is to try to use as many new words as possible in the correct manner.

Answers
Words in Context
The paragraph is a recollection of a visit to see the apes and the behaviors noticed by the narrator; thus we should certainly conclude that simian means apelike or concerning apes. When we read that some apes remained diffident but others came forward to greet the visitors, we can understand that diffident could mean shy or reserved. The friendly ape that offers food in his prehensile hand must surely have a hand that is capable of holding something. Since the leader of the apes remains a stolid observer of all the activities, we can guess that he is showing no emotion or expression, because he is juxtaposed with his fellow apes who get excited. The apes that become scared when the leader moves about cower in the corner, so we can understand that they are cringing and trembling in fear of him. The two apes that fight during the visit apparently have rancor only for each other, so we should know that rancor means hatred or ill will. The ape Yankee seems to be staring at the door and trying to figure out a means of escape, so we can conclude that ruminate means to think over or ponder. Yankee's attempts to extricate himself from the cage, despite it being impossible without the keys, indicate that extricate must mean free or release. Finally, since we are told Yankee is resolute enough to continue his attempt for hours, we can understand that resolute must mean determined and firm of purpose.

- c. furious. Diffident means shy and reserved. Since furious means violently angry and raging, it is not a synonym.
- d. average. Anomaly means an irregularity or abnormality. Since average means usual or commonplace, it is not a synonym.
