Juanita and Sam attend a beach party and notice that the local beach appears to have a great deal more trash washed up on shore than it did when they were young. The water doesn't appear nearly as clear, and there seems to be less evidence of small water creatures living in the shallows. An afternoon at the local library convinces them that one major cause is the new factory nearby. After some discussion, they decide their next step should be ________. identifying the cause of the changes identifying the problem picketing the guilty factory lobbying their elected representatives to complain about the problem talking to a local environmental group about solutions

This option is the best one for Juanita and Sam to take since they both need someone who have more expertise in this field to help them determine the best solution to the problem that they encounter, which is sea trash. The other options are unsuitable because they do not provide direct impact (such as picketing the guilty factory), unrealistic (lobbying their elected representatives), or have been done (identifying the changes and problem).
