The correct answers are "were" and "is". The mummies were an important discovery, but the real story is the stone tablets.

Explanation:

According to grammar, it is required for sentences to have a noun and verb agreement, this implies the form of the verbs need to be modified according to the subject that precedes it or that is placed before the verb. This implies if the subject is singular, that means it expresses only one object, concept, animal or person, the verb should be singular as well, in the same way, if the subject is plural the verb should be plural. In this way, in the sentence presented the first subject is "the mummies" considering this is a plural subject as it refers to more than one mummy the correct form of the verb is "were" as this is the past form of the verb "to be" that is used for plural nouns. Similarly, for the second noun "real story" the correct form is "is" as the form "is" is used for singular nouns and "real story" refers to only one story.
