yellow group · The short answer
CUTTING-EDGE
Each puzzle word passes the same exact test. The four mappings show how the answer works.
ADVANCED describes something that has reached a highly developed or leading stage.
FOREMOST identifies something regarded as leading, most prominent or most important.
MODERN can describe something based on current ideas, methods, designs or technology.
PROGRESSIVE describes something that develops, improves or promotes forward movement.
Why this group was difficult
- Each adjective has broader everyday uses
The words can refer to age, importance, style or reform, so their common leading-edge sense is not automatic. - COMPLEX looks like another plausible adjective
COMPLEX can join a loose set of descriptive words, but it does not specifically mean cutting-edge. - The relationship depends on sense selection
Each answer must be read in a forward-looking or field-leading sense rather than merely as a positive descriptor.
How to spot this pattern next time
When several adjectives appear, replace each one with the proposed category phrase and check whether the resulting description remains natural and precise.
Reject sets held together only because all four words can modify the same vague noun; look for a shared meaning rather than shared grammar.
Four useful facts behind the group
- All four official answers function naturally as adjectives.
- The category uses a figurative sense of an edge as a leading position.
- COMPLEX is descriptive but does not carry the required leading-edge sense.
- FOREMOST emphasizes leadership more than recency alone.
