input: Please answer the following: Extract the answer to the question from the following context. Question: Which weighs more, air or a human? Context: A solar balloon is a black balloon that is filled with ordinary air. As sunlight shines on the balloon, the air inside is heated and expands causing an upward buoyancy force, much like an artificially heated hot air balloon. Some solar balloons are large enough for human flight, but usage is generally limited to the toy market as the surface-area to payload-weight ratio is relatively high.

input: Please answer the following: Extract the answer to the question from the following context. Question: Trans-splicing and alternate splicing, which one is used for one gene to form new genes? Context: Early work in molecular genetics suggested the model that one gene makes one protein. This model has been refined since the discovery of genes that can encode multiple proteins by alternative splicing and coding sequences split in short section across the genome whose mRNAs are concatenated by trans-splicing.
