Question

question 45
the \tri - plex\ syringe is named that because:
it was developed in triplex, germany
it is held by the 3rd finger of the left hand
it can be used for water, air or spray
it can be used by 3 people in the dental team

Explanation:

To determine the correct answer, we analyze each option:

• Option 1: There's no indication the syringe was developed in Triplex, Germany. This is likely incorrect.
• Option 2: Holding it with the 3rd finger doesn't relate to the "tri - plex" name (which implies three functions/uses).
• Option 3: "Tri - plex" suggests three functions. Using it for water, air, or spray gives three distinct uses, matching the "tri - " (three) in the name.
• Option 4: A syringe being used by 3 people in a dental team is not a typical reason for naming it "tri - plex".

Answer:

C. it can be used for water, air or spray
