blue group · The short answer
THINGS THAT ARE TOWED
Each puzzle word passes the same exact test. The four mappings show how the answer works.
A BARGE without its own effective propulsion may be pulled along a waterway by a tugboat or another powered vessel.
A GLIDER can be launched by being pulled into the air behind a powered tow plane before the tow line is released.
A TRAILER is designed to travel behind a car, truck or other vehicle that supplies the pulling power.
A WATER SKIER travels across the water while holding a tow rope connected to a moving motorboat.
Why this group was difficult
- The settings do not match
The examples belong to waterways, aviation, roads and recreation, so they do not resemble one another as objects. - A strong water set distracts
BARGE and WATER SKIER can join SURF and WAVES in a plausible but incomplete water-related grouping. - One answer is a person
WATER SKIER differs grammatically from the three object nouns, which can obscure the shared action applied to all four.
How to spot this pattern next time
When leftover nouns come from unrelated settings, test a shared action that can be performed on each rather than seeking one physical class.
Check whether a proposed verb works literally for every candidate; here, each answer can directly and conventionally be described as towed.
Four useful facts behind the group
- A BARGE may be moved by a tug when it lacks suitable propulsion.
- A GLIDER can use an aerotow to gain altitude before free flight.
- A TRAILER follows the towing vehicle through a hitch connection.
- A WATER SKIER holds a tow rope while moving over the water.
Questions players ask
The details people search after seeing the group
What connects BARGE, GLIDER, TRAILER and WATER SKIER?
Each is something that can be pulled along by another powered vehicle or craft, matching THINGS THAT ARE TOWED.
How is a GLIDER towed?
A powered aircraft can pull a GLIDER upward with a tow line, which is released after the desired altitude is reached.
Why does WATER SKIER fit with vehicles and craft?
The category concerns what receives the towing action, so it can include a person as well as vessels, aircraft and road equipment.
What was the strongest red herring in this group?
BARGE, SURF, WAVES and WATER SKIER form an appealing water theme, but that theme lacks the exactness of the verified groups.
