Question

which statement is the most effective claim?
organic foods are a healthier option than conventional foods.
it is easier to find organic foods than to find conventional foods.
restaurants are beginning to serve more organic foods.
some think that organic foods are tastier than conventional foods.

Explanation:

A claim should be debatable and specific. "Organic foods are a healthier option than conventional foods" is debatable as it can be argued for or against with evidence. The other statements are either too easily verifiable (e.g., "It is easier to find organic foods than to find conventional foods" - can be checked by looking at store availability) or not as strongly debatable (e.g., "Restaurants are beginning to serve more organic foods" - a simple observation; "Some think that organic foods are tastier than conventional foods" - a subjective opinion of "some" which is not as strong a claim as a general statement about health).

Answer:

Organic foods are a healthier option than conventional foods.
