True. Ancient Greek romances are today recognised as novels. Even though there are only five of them preserved completely, many more fragments have survived. The most notable among those preserved Greek novels are Longus' "Daphnis and Chloe" and Heliodorus' "Aethiopica". As for Spanish adventure stories, the so-called Picaresque novel of the 16th century was extremely popular. It is much closer to our own understanding of a novel - it doesn't deal with mythology, but realistic characters from lower social classes, and their adventures.
The statement that best summarizes the central idea of the text is -The actions of a large group can greatly influence an individual’s decisions.
Explanation:
When a person/individual is in a group the decision making ability of the person is influenced by the people of the group or the group members.
The perspective of the members of the group has a great say in the decision making skill of the individual member.
When an individual is alone or not a part of the group then his perspective of looking at the things is far different but once he becomes a part of the group he consider the perspective of the other individuals as well and thus the decision is influenced by the group members.
I think you described a typical gerund. In English we use -ing form for verb to make a noun in a sentence. For instance, my brother usually listens his favorite songs when driving. The last word 'driving' is gerund from a verb 'to drive'.
