Subject: [PATCH 2/2] Added two additional examples to Filtering and
 Conditional Operators: "single with conditions".

Per suggestion by @scotteg, two additional examples were added to cover the following use cases:

* A successful matching case of exactly one element
* An error when repeated elements are observed
