What i gave you was supposed to … your monthly earnings

Analyze the question The sentence is: "What I gave you was supposed to ..... your monthly earnings." We need a verb that means to add to or increase something that already exists, in this case your income.

Explain the concept This is a vocabulary-in-context question. The words look similar, but each collocates with different objects:

• Expand: to make something bigger in size or scope (expand a business, expand a market). We don't normally say "expand earnings."
• Enlarge: to make something physically bigger (enlarge a photograph, enlarge a room). It is not used for money.
• Complete: to finish something or make it whole. It would mean the money finishes your earnings, which doesn't fit the logic.
• Augment: to add to something in order to increase it (augment your income, augment your salary). This is the standard collocation for money.

Solution The money given was meant to supplement the monthly earnings, which means to add to them and boost them. "Augment" has exactly this meaning:

"What I gave you was supposed to augment your monthly earnings."

Tip Remember the pairing augment = add to income or supply. "Augment" and "supplement" are close in meaning. When you see money, salary, or earnings in a sentence, look for words like augment, supplement, or boost. Use "enlarge" for physical size and "expand" for business or scope.
