Problem: Text: Sun-dried tomatoes are ripe tomatoes that lose most of their water content after spending a majority of their drying time in the sun. These tomatoes are usually pre-treated with sulfur dioxide or salt before being placed in the sun in order to improve quality. Typically, tomatoes spend 4--10 days in the sun in order for the sun-drying process to be complete. Cherry types of tomatoes will lose 88% of their initial (fresh) weight, while larger tomatoes can lose up to 93% during the process. As a result, it takes anywhere from 8 to 14 kilograms of fresh tomatoes to make a single kilogram of sun-dried tomatoes.

Question: are sun dried tomatoes really dried in the sun?
A: yes

Problem: Text: Euryhaline organisms are able to adapt to a wide range of salinities. An example of a euryhaline fish is the molly (Poecilia sphenops) which can live in fresh water, brackish water, or salt water. The green crab (Carcinus maenas) is an example of a euryhaline invertebrate that can live in salt and brackish water. Euryhaline organisms are commonly found in habitats such as estuaries and tide pools where the salinity changes regularly. However, some organisms are euryhaline because their life cycle involves migration between freshwater and marine environments, as is the case with salmon and eels.

Question: can some fish live in both saltwater and freshwater?
A: yes
