Difficulty: EasyInferring Vocabulary Meaning from Context

Before operating a newly repaired hydraulic lift, maintenance personnel must carefully bleed the fluid lines. Trapped air pockets inside the closed system can cause erratic movement and prevent the cylinders from holding pressure properly. Opening the release valve allows the trapped air to escape until a solid stream of fluid appears, ensuring smooth and reliable mechanical operation.

As used in the passage, the word "bleed" most nearly means to

  1. A
    lose blood from a physical wound
  2. release trapped air or fluid from a closed systemAnswer
  3. C
    pump pressurized fluid into a reservoir
  4. D
    stain or discolor an external surface

Answer

Release trapped air or fluid from a closed system
In this context, 'bleed' refers to the mechanical maintenance procedure of opening a valve to let unwanted air pockets escape from hydraulic lines so the system functions properly.

Step-by-Step Solution

1
Examine the surrounding context to identify clues explaining the action.
The text mentions that opening the release valve allows trapped air to escape until a solid stream of fluid appears.
Surrounding sentences define the function and purpose of the target action.
2
Select the option that matches the action of allowing trapped air or fluid to escape.
Releasing trapped air or fluid from a closed system precisely describes the procedure.
The correct answer must reflect the mechanical operation described in the paragraph.
