This is a two-blank text completion question that tests:
- Scientific Context: Understanding how influenza strains spread globally.
- Vocabulary: Words like "seeded," "dissemination," and "derivation" must fit the epidemiological context.
- Logical Flow:
- Blank (i): How the strains originated/spread.
- Blank (ii): The result of increased travel to Asia.
Approach:
1. Blank (i): "Strains have been [blank] viruses from China/Vietnam."
(A) decimated by (destroyed) $\(\rightarrow\)$ Incorrect; contradicts "originated."
(B) decomposed in $\(\rightarrow\)$ Nonsensical; viruses don't decompose.
(C) seeded by (originated from) $\(\rightarrow\)$ Fits; implies viral origins.
2. Blank (ii): "Their [blank] was generated by increased travel."
(D) dissemination (spread) $\(\rightarrow\)$ Fits; travel facilitates viral spread.
(E) derivation (origin) $\(\rightarrow\)$ Incorrect; already addressed in Blank (i).
(F) diminution (reduction) $\(\rightarrow\)$ Contradicts the spread narrative.
Correct Pair: (C) seeded by, (D) dissemination.
