Complete the sentence with a four-word defining clause: The panel ___ needs a new fuse. Use that followed by the verb controls and the noun phrase the pumps, with no added words.
الإجابة الصحيحة
that controls the pumps
الشرح
That supplies the subject of controls and links the identifying information directly to the panel. Leaving that out would be the closest error because there would be no subject for controls.
