Question: passage: Citric acid can be added to ice cream as an emulsifying agent to keep fats from separating, to caramel to prevent sucrose crystallization, or in recipes in place of fresh lemon juice. Citric acid is used with sodium bicarbonate in a wide range of effervescent formulae, both for ingestion (e.g., powders and tablets) and for personal care (e.g., bath salts, bath bombs, and cleaning of grease). Citric acid sold in a dry powdered form is commonly sold in markets and groceries as ``sour salt'', due to its physical resemblance to table salt. It has use in culinary applications, as an alternative to vinegar or lemon juice, where a pure acid is needed.
 question: can lemon juice be used as citric acid?

Answer: Yes


Question: passage: Fez's secret country of origin is one of the longest running gags on the show. Through all eight seasons, Fez's nationality remains a mystery, even to his closest friends, and the continual hints and clues Fez drops about his country only leave them more confused. In the episode ``Eric's Birthday,'' Kitty, fantasizing about Eric's friends causing trouble, imagines Fez saying, ``in my home country of...wherever it is I'm from; I can never tell...'' Much is revealed in the episode ``Love of My Life,'' where one of Fez's compatriots (played by Justin Long) comes for a visit. In the first teaser, when his friend suggests that he goes home, he says ``Yes, I will go to Brazil...and then catch a flight home.'' In the final teaser, when Hyde finally asks them, ``Where the hell are you guys from?'', his friend says that the name depends on whether you ask the British or the Dutch. But the British won't say it, Fez explains, because they hate the island, and no one understands a word the Dutch say. The friend has a heavy English accent; Fez's explanation to this is that his friend is from the west side of the island. We also see throughout the show that Fez almost says where he is from but then stops right before he says it.
 question: do we find out where fez is from?

Answer: No
