------------------------------------------------ The code:

```java
double[] grades = { 98.3, 62.7, 83.6, 51.9 };
double[] scores = grades;
```

creates _ set(s) of contents and _ reference value(s).

The code creates one set of contents (the array of grades) and two reference values (grades and scores) that point to the same memory location.

Explanation:

In the context of the code displayed, there is only one set of contents, represented as the array of grades: { 98.3, 62.7, 83.6, 51.9}. However, there are two reference values, represented by the variables 'grades' and 'scores'. Each reference value points to the memory location of the contents. Thus, when the 'scores' array is modified, the 'grades' array is also altered, as they both refer to the same contents.

This akin to having two different names (reference values) for the same person (contents). Regardless of which name you use, you're referring to the same individual.
