Answer:
The answer is true.
Step-by-step explanation:
Some adjectives, such as "concerned" change their meaning according to their position in the sentence.
For example:
Concerned before a noun means "worried" [Cambridge Dictionary] (I'm a bit concerned about/for your health). However, adopted after a noun means "involved in something or affected by it" [Cambridge Dictionary] (I'd like to thank everyone concerned for making the occasion run so smoothly)
