Would you please help me find topic sentence?
Hi.
I am supposed to find the topic and topic sentence of these paragraphs:
There is a possible solution to the problem of "sick" buildings. A scientist at NASA (National Aeronautical and Space Administration) was trying to find ways to clean the air in space stations. He discovered that houseplants actually remove pollutants from the air. Certain plants seem to do this better than others. Spider plants for example appear to do the best job. Even defoliated plants (without leaves) worked well! In another study, scientists found that the chemical interaction among soil, roots, and leaves works to remove pollutants.
Topic: a possible solution
Topic sentence: There is a possible solution to the problem of "sick" buildings.
This seems like a good solution, but we don't know enough yet. There are many questions. For instance, which pollutants can plants remove? Which can't they remove? How many plants are necessary to clean the air in a room-- one or two or a whole forest of plants? When we are able to answer these questions, we might find that plants offer an important pollution-control system for the 21st century.
Topic: we don't know enough
Topic sentence:This seems like a good solution, but we don't know enough yet.

Now do you have any idea what the paragraph is about?

My second try:
Topic: a possible solution to the problem of "sick" buildings.
Topic sentence: There is a possible solution to the problem of "sick" buildings.
And for the other paragraph:
Topic: lack of information about houseplants
Topic sentence: houseplants seem like a good solution, but we don't know enough yet.
Topic: a possible solution to the problem of "sick" buildings.
Topic sentence: There is a possible solution to the problem of "sick" buildings.
And for the other paragraph:
Topic: lack of information about houseplants
Topic sentence: houseplants seem like a good solution, but we don't know enough yet.

And what about this paragraph?
A recent study reached a surprising conclusion: Indoor air pollution is almost two or five times worse than outside pollution! This is true even in buildings that are close to factories that produce chemicals. Better ventilation-- a system for moving fresh air-- cant cut indoor pollution to a safe level, but lack of ventilation is seldom the main cause of th
