Answer 1

The correct conjugation to the verbs is:

Sentence 1: Raised

Sentence 2: Rise

Step-by-step explanation:

The first sentence uses a time expression that is referring to the past " In 1960" reason why is necessary to follow a simple past structure in the sentence, the correct sentence is "In 1960 American scientists RAISED a serious concern", the keyword for the second sentence is the frequency adverb "always", these words are used to demonstrate routinary activities, therefore the sentence has to follow a simple present structure, then the correct sentence is "Her rolls always RISE properly."

Answer 2

In the first sentence, it refers to 1960 which tells that the event has happened already so the verb that should be used should be of past tense. In this case, the correct verb should be raised. In the second statement, always refers to regular or present tense verbs. The answer is rise : no change.
