1. list as many words as you can think of that begin with the prefix con.
2. list as many words as you can think of that contain the suffix ator.

Explanation:

1.

• A. "ex -" means "out" and "pel" means "to push", so "expel" is to drive out.
• B. "dis -" means "apart" and "pel" means "to push", so "dispel" is to drive apart.
• C. "propeller" has "pel" (to push), a propeller is a device that pushes.
• D. "con -" means "with/together", "sum" means "take", and "-ion" means "the act of", so "consumption" is the act of taking together (using up).
• E. "sumpt" means "take", "sumptuous" means characterized by great expense (taking a lot).
• F. "ac -" is an intensifier, "celer" means "swift", and "-ator" means "one who does", so "accelerator" is one who makes swift.

1. Since "celer" means "swift", someone moving with celerity is moving quickly. "Accelerate" means to move faster. The opposite of accelerating (slowing down) is decelerating.
2. Taking excerpts from career history and writing them down creates a summary (using "sum" - take). And one should not assume (a common word - not directly related to the roots but a logical fill - in) that someone will hire without an interview.
3. Driving something forward is propelling (using "pel" - to push). Driving something back could be repelling (re - can mean back, and "pel" - to push). A salesperson might persuade (using "suade" related to influencing, not directly from given roots but a common word for sales action), a threat to safety would compel (using "pel" - to drive someone to take cover). One would dispel (using "dis -" and "pel") rumors.
4. Words starting with "con -" include: connect, combine, convene, confirm, construct.
5. Words with the suffix "-ator" include: operator, elevator, generator, calculator, excavator.
