The third option is correct.
Answer:
How does second hand smoke affect our health?
Explanation:
The other three questions can be answered with a simple 'yes' or 'no' .... or a simple one-word response; whereas, the second-hand smoking question requires an open-ended response.
One afternoon, an old man ordered in a nearby restaurant for breakfast.
He went inside, find a seat and sit comfortably.
Then one smiling waiter approached him and asked: "What's your order for this morning, sir?" The old man replied, "Can I have one rubbery egg and two slices of burnt toast, please?"
The waiter with his two brown eyes glow with awe, answered, "One rubbery egg and two slices of burnt toast? (with an emphasis on the word "rubbery and burnt") Was that correct sir?" "Yes, you just said it right", the man replied.
"Why on earth would you want such a dish?" asked the waiter.
"My wife was out of town and I missed her cooking." replied the old man.
"Oh! I see". the waiter answered with a smirk and walk back scratching his head.
The conjunction would be "so" its used to join 2 sentences together to make one complete thought.
