To determine which underlined word has connotations most clearly opposite to "gash" as Reagan uses it, we should consider the context and emotional or figurative implications of each word.
A. "Laceration" generally conveys a severe or harmful cut, similar to "gash," without a positive connotation.
B. "Incision" is a clinical term often associated with precision and care in surgical contexts. It does not carry the same violent or destructive connotation that "gash" might suggest.
C. "Gouge" implies a harsh or damaging cut, which aligns more closely with the negative undertones associated with "gash."
Among these options, “incision” (B) has connotations that are most opposite to "gash." While both words reference a cut, "incision" is associated with careful medical procedures, suggesting skill and control, rather than the destructive or violent implications of "gash."
Therefore, the answer is B. incison.
