Answer:
6. C: change dangers to danger's
Explanation:
Abused people respond well to love, but they usually don't believe it's real. They wonder why they aren't being hurt or why there is no pain in their love. If they are in a relationship with someone who abuses them, and they never got help as a child, they will continue to be abused and hurt. If they did get help as a child, they will, most likely, walk out of the relationship. On the other hand, people who had good childhoods will respond 'normally' to love, getting out of bad relationships, and staying in good ones.
The subjunctive mood is the best.
The subjunctive is rarely used in colloquial English. Totally irrelevant information, but... it is a relic from Latin, where there are many uses for a subjunctive. There is even a special conditional using the subjunctive mood that expresses the exact circumstances you described, which is usually called future less vivid.
