Read the persuasive conclusion. gardening can enhance lives and provide nourishment. time spent outside in a garden boosts the body’s immune system, and a garden’s harvest can be a healthy, cost-saving supplement to any diet. which sentence best completes this conclusion? the sun is a natural source of vitamin d, an essential nutrient for good health. when tending your garden, use natural pesticides instead of chemicals. consider starting your own garden with some of your favorite vegetable seeds. despite the challenges of insects and blight, gardening is a simple hobby.

The sentence which best completes this conclusion is the following: Consider starting your own garden with some of your favorite vegetable seeds.

This is because the rest of the conclusion paragraph refers to benefits that gardening can offer. So, a concluding sentence which encourages the readers to start their own garden is the only relevant choice here. Choice 1 talks about the benifits of the sun exposure but it's not directly related to gardening. Choice 2 gives a very specific advice on pesticides which doesn't seem to be relevant at this point either. Choice 4 mentions some challenges that gardening has and so it cannot be used to finish a parapraph related to the benefits of gardening.
