2. This is the next more difficult single and plural test center. Remember this better: the unique things that can be enjoyed emotionally are: a feeling, a desire, a dependence ... and the plural things that can't be enjoyed physically are: raising your voice, changing your mind and winning people's hearts.
In fact, it is a parallel simplification, that is, it is an organization that not only provides things for lovers, but also gives them things. Parallel components-components for couples-gifts. Their reference discount is clear to them here (mind you, your C is wrong ...)
