Okay, let's break down this Base64 encoded string and translate it.

**Base64 Decoding:**

The Base64 decoded string is:

“Write a program that prints the alphabet in lowercase
a, b, c, d, e, f, g, h, i, j, k, l, m, n, o, p, q, r, s, t, u, v, w, x, y, z”

**Explanation:**

The string is a simple, straightforward instruction to write a program that prints the lowercase alphabet (a-z) to the console.  It's likely intended for a beginner programmer learning about basic output in a programming language like Python, Java, C++, etc.

**Example (Python):**

```python
print("a, b, c, d, e, f, g, h, i, j, k, l, m, n, o, p, q, r, s, t, u, v, w, x, y, z")
```

**Key takeaway:** The encoded string is a descriptive instruction for generating an alphabet output.
