    Question

    The increased caseload and mortality due to the disease this year compared with last year could be because pre-existing immunity through exposure to the California strain is no longer effective, and people are therefore not immune to the new strain.

    I. All diseases cause mortality.

    II. California strain is more effective than the new strain.

    A If only assumption I is implicit Correct Answer Incorrect Answer
    B If only assumption II is implicit Correct Answer Incorrect Answer
    C If either I or II is implicit Correct Answer Incorrect Answer
    D If neither I nor II is implicit Correct Answer Incorrect Answer
    E If both I and II are implicit. Correct Answer Incorrect Answer

    Solution

    Only one disease is being talked about, nothing about the effect of all the diseases has been mentioned. Thus I is not implicit. Also, the comparison between the strength of the two strains on individual level is not mentioned. Thus, II is also not implicit.
