Alternative is a choice between —— things.

Avocation, vocation.

1. My regular calling, or vocation, is teaching; but for an avocation I spend my holidays in photography.

2. Dr. Weir Mitchell is a physician; but his regular vocation of medicine doesn’t prevent him from following the delightful avocation of letters.

Both these words have the idea of calling. Explain how they differ. (What does ab mean in Latin?)

Balance, remainder.

1. The balance of the sum is due.

2. The remainder of the day is spent.

What relation exists between balancing (a book) and remainder?
