Difficulty: HardQuantifier Logic (Some, Most, All)

Match each set of formal premises concerning ancient linguistics and archaeology to the logically valid deduction that must follow from it.

  • All translated scrolls from the Qumari archive discuss astronomical phenomena. Furthermore, most of the translated scrolls from the Qumari archive were authored by temple priests.At least some works authored by temple priests discuss astronomical phenomena.
  • Most scholars specializing in Qumari syntax are proficient in early Veldtian dialects. Additionally, most scholars specializing in Qumari syntax have published peer-reviewed research.At least some individuals who have published peer-reviewed research are proficient in early Veldtian dialects.
  • Every known Veldtian dialect employs a base-eight counting system. However, some known Veldtian dialects lack dedicated future-tense verb forms.Some dialects that utilize a base-eight counting system do not possess dedicated future-tense verb forms.
  • Most excavated Veldtian trade outposts contained mercantile ledgers. Every excavated Veldtian trade outpost that contained mercantile ledgers was situated along a major coastal route.More than half of the excavated Veldtian trade outposts were situated along a major coastal route.

Answer

Setup 1 matches with the inference about works authored by temple priests. Setup 2 matches with the inference about published individuals being proficient in Veldtian dialects. Setup 3 matches with the inference about base-eight dialects lacking future tense. Setup 4 matches with the inference about the majority of outposts being on coastal routes.
Each correct pairing strictly follows formal quantifier logic rules without introducing outside assumptions. The overlaps of 'All/Most', 'Most/Most', and 'All/Some' establish mathematically guaranteed intersections, while the 'Most/All' chain allows a valid transitive 'Most' deduction.

Step-by-Step Solution

1
Analyze the first set of premises: All Q are A, and Most Q are P.
Deduce that because more than half of Q is P, and 100% of Q is A, there must be an overlap. Therefore, Some P are A.
Combining an 'All' and a 'Most' statement about a shared sufficient condition always yields a 'Some' conclusion.
2
Analyze the second set of premises: Most S are V, and Most S are R.
Deduce that two majorities of the same group must intersect. Therefore, Some R are V.
If >50% of a group has trait X, and >50% has trait Y, at least one member must have both traits.
3
Analyze the third set of premises: All V are B, and Some V are not F.
Deduce that the specific 'V's that are not 'F' must still be 'B'. Therefore, Some B are not F.
A 'Some' statement introduces an existing subset, which inherits all universal ('All') traits of the parent group.
4
Analyze the fourth set of premises: Most O are L, and All L within O are C.
Deduce that because the subset L makes up most of O, and all L are C, C must also make up most of O. Therefore, Most O are C.
This is a restricted transitive property where a universal condition applied to a majority subset transfers the majority status to the conclusion.

Key Concept

Logical deduction using combinations of 'All', 'Most', and 'Some' quantifiers to determine guaranteed overlaps.
