Read the given sentence. Identify the error and supply the correction in the sentence.
Ninety-seven percent of the Earth’s water is salty ocean water and another two percent is trapping in the Earth’s ice caps and glaciers. 
The verb “is trapping” is incorrect because it implies an active ongoing process. However, the sentence describes a state, so the correct form is the passive “is trapped.”
Error: is trapping
Correction: is trapped
Using the passive form “is trapped” accurately reflects that the subject is receiving the action rather than performing it.
This distinction is important for clear and grammatically correct expression, especially when describing conditions or states.
Always choose the verb form that best matches whether the action is active or passive in the context of the sentence.
