Name two major types of agriculture.

The identification of conventional and organic agriculture as two major types of agriculture is correct because these classifications represent different approaches to farming that are widely recognized and practiced.

Conventional agriculture typically refers to farming methods that involve the use of synthetic fertilizers, pesticides, and herbicides, aimed at mass production and high yields. This approach often relies on mechanization and monoculture practices, where a single crop is grown extensively in a given area.

On the other hand, organic agriculture emphasizes environmentally sustainable practices, avoiding synthetic chemicals and genetically modified organisms (GMOs). Instead, it relies on natural inputs, crop rotations, and biodiversity to maintain soil health and ecosystem balance. This approach caters to consumer demand for food that is perceived as healthier and more environmentally friendly.

The other choices, while they describe valid categories in agriculture, do not capture the primary distinction and wide acceptance found between conventional and organic farming practices. For instance, commercial and subsistence agriculture focus more on the scale of production rather than farming methods; sustainable and industrial agriculture touch on broader concepts of sustainability and production intensity but do not highlight the method-oriented perspective of farming practices. Therefore, conventional and organic agriculture stand out as two major, contrasting approaches with significant implications for agricultural practices, policy, and consumer choices.
