The question deals with the use of language. The excerpt describes a mission of an organization. The mission generalizes the sole purpose of an organization. Additionally, we can observe that this is the mission of a social organization which highlights true and profound feelings. Therefore, the tone of the excerpt is sincere.
THE ANSWER IS B I HOPE IT IS CORRECT
This sentence is incorrect because it is a run-on sentence. This means that it should be broken into two separate sentences:
Ladybugs are also called lady beetles. In Europe, they are called ladybird beetles.
It's easy to catch this mistake by either reading the sentence out loud and listening for a natural pause, or by looking for one subject and one verb per sentence (Ladybugs are; they are).
