Problem Analysis #9

[THOUGHT] The problem asks us to identify the correct understanding of the <Data> (자료) based on the rules provided in the <Box> (보기).

Analysis of <Box> (Rules):

1. Contextual Adjustment: When converting to indirect quotation, personal pronouns, demonstratives, and time expressions in the original utterance are adjusted according to the context of the reporting sentence.
2. Sentence Endings: Relative honorific endings (polite/formal levels like Haeyo-che, Hasipsio-che) are neutralized into specific indirect quotation forms based on sentence type:
   • Declarative (평서) $\rightarrow$ -다고
   • Interrogative (의문) $\rightarrow$ -냐고
   • Imperative (명령) $\rightarrow$ -라고
   • Propositive (청유 - "Let's") $\rightarrow$ -자고
   • Exclamatory (감탄) $\rightarrow$ Treated as Declarative (-다고)

Analysis of Options:

• ① ㉠: "He" said "the day before yesterday" (그제) that "let's clean together today (오늘)."

  • In indirect speech, time expressions are adjusted to the reporter's perspective. The reporter says "today" (Day T).
  • The original speech happened "the day before yesterday" (Day T-2).
  • From the perspective of the original speaker on Day T-2, the current "today" (Day T) was "the day after tomorrow" (모레).
  • Therefore, the original utterance likely used the word "모레" (e.g., "모레는 청소를 같이 하자").
  • The option states it cannot be a quotation of an utterance with '모레는'. This is incorrect.

• ② ㉠: The quoted ending '하자' (in 하자고) could be an indirect quotation of '해요'.

  • The indirect ending '-자고' indicates a Propositive sentence (Let's...).
  • The original ending '해요' (Haeyo-che) is an informal polite ending that can function as declarative, interrogative, imperative, or propositive depending on context and intonation.
  • Example: "우리 같이 청소 해요" (Let's clean together).
  • According to the <Box>, regardless of the original politeness level, a propositive sentence becomes '-자고'.
  • Thus, "청소 같이 해요" $\rightarrow$ "청소 같이 하자고".
  • The option states it could be. This is correct.

• ③ ㉡: "Kim Teacher" said to students that "he himself (자기)" likes poetry.

  • "자기" in indirect quotation is a reflexive pronoun referring to the subject of the reporting sentence (Kim Teacher).
  • This transformation occurs when the subject of the original direct speech is the 1st person ("I" / "나", "저").
  • Example: Kim Teacher said, "I like poetry." $\rightarrow$ Kim Teacher said that he (self) likes poetry.
  • If the original had a 2nd person subject ("You"), it would refer to the listeners (students) and would be reported as "they" or "students", not "자기" (which refers back to Kim Teacher).
  • The option states it could be a quotation of a 2nd person subject. This is incorrect.

• ④ ㉡: The quoted word '좋아한다' (in 좋아한다고) cannot be an indirect quotation of '좋아합니다'.

  • The indirect form is '-다고' (Declarative).
  • '좋아합니다' is a formal polite Declarative form.
  • According to the <Box>, declarative sentences merge into '-다고'.
  • "좋아합니다" $\rightarrow$ "좋아한다고".
  • The option states it cannot be. This is incorrect.

• ⑤ ㉢: The quoted word '있겠냐고' cannot be a quotation of an utterance with a future tense pre-final ending.

  • The indirect quote contains '겠' (in 있겠냐고).
  • '겠' is a pre-final ending often indicating future or conjecture.
  • Indirect quotation generally preserves these pre-final endings from the direct speech.
  • Original: "내일 퇴원을 할 수 있겠니?" (Will you be able to...?)
  • Indirect: "...할 수 있겠냐고".
  • The option states it cannot be. This is incorrect.

Conclusion: Only option ② is a correct understanding.

\boxed{②}
