Input: Article: The terms asphalt and bitumen are often used interchangeably to mean both natural and manufactured forms of the substance. In American English, asphalt (or asphalt cement) is the carefully refined residue from the distillation process of selected crude oils. Outside the United States, the product is often called bitumen. Geologists often prefer the term bitumen. Common usage often refers to various forms of asphalt/bitumen as "tar", such as at the La Brea Tar Pits. Another archaic term for asphalt/bitumen is "pitch".

Now answer this question: Where is bitumen the usual term for refined residue from crude oils?

Output: United States

Input: Article: Presbyterianism is historically a confessional tradition. This has two implications. The obvious one is that confessional churches express their faith in the form of "confessions of faith," which have some level of authoritative status. However this is based on a more subtle point: In confessional churches, theology is not solely an individual matter. While individuals are encouraged to understand Scripture, and may challenge the current institutional understanding, theology is carried out by the community as a whole. It is this community understanding of theology that is expressed in confessions.

Now answer this question: How is theology carried out in a confessional church?

Output: by the community as a whole

Input: Article: Fossilized spores suggest that higher plants (embryophytes) have lived on land for at least 475 million years. Early land plants reproduced sexually with flagellated, swimming sperm, like the green algae from which they evolved. An adaptation to terrestrialization was the development of upright meiosporangia for dispersal by spores to new habitats. This feature is lacking in the descendants of their nearest algal relatives, the Charophycean green algae. A later terrestrial adaptation took place with retention of the delicate, avascular sexual stage, the gametophyte, within the tissues of the vascular sporophyte. This occurred by spore germination within sporangia rather than spore release, as in non-seed plants. A current example of how this might have happened can be seen in the precocious spore germination in Selaginella, the spike-moss. The result for the ancestors of angiosperms was enclosing them in a case, the seed. The first seed bearing plants, like the ginkgo, and conifers (such as pines and firs), did not produce flowers. The pollen grains (males) of Ginkgo and cycads produce a pair of flagellated, mobile sperm cells that "swim" down the developing pollen tube to the female and her eggs.

Now answer this question: Upright meisporangia allowed what to be dispersed to new habitats?

Output:
spores
