' He was terrified, for
he had never expected to find empty space underneath the world.
But his wife was filled with curiosity.'
"The man who was almost a man" speaks of Dave, who had conflicts with gaining recognition and respect, because he was young. He wanted to grow up and become a man. For this he bought a weapon, thinking that it would make him grow as a man. Seeking power, he buys this weapon, to feel powerful, unstoppable. All these conflicts of the dave age led him to make some bad decisions. The story well specifies this when he accidentally shoots a mule, and he cannot sustain the excuse he made up for it, and when he decides to take a train and go to a city where he would be able to man up.
The proper way to write the sentence would be "However, no one believed rumors about the Komodo dragon either." Since commas are used after words like "first, second, third, then, finally, however, but..." there would only be 1 comma in this sentence.
I hope this helps!!
I believe that the best answer for this question is "are." You are referring to two parties here, both the lion tamer and the clowns. This would mean that your applicable verbs must also be plural. Since "are" is the plural version of "is," it is the most suitable word to use in this situation. Hope this helps.
