Hi! Your sentence “What do we take objects by?” sounds a little odd. Here are easier and better ways to ask the same idea:
- How do we pick up objects? (very natural)
- What do we use to pick up objects?
- What do we pick up objects with? (also OK, but we usually say “How do we pick up…?”)
Why? Because in English we usually use with to say what tool or body part does the action: “We pick up a cup with our hands.” We can also say the short phrase by hand (meaning using hands), but we don’t normally put by at the end like in your sentence.
More examples:
- We pick up a pencil with our fingers.
- We carry a bag with our hands.
- We hold someone by the hand (this is a special phrase: “by the hand” means you hold their hand).
Try this practice question: How do you pick up a spoon? A good answer: With my hand.
