Given a paragraph about cooking, and a set of conversational question answers about the paragraph, answer a follow-up question from the paragraph. The paragraph has a prefix 'CONTEXT:'. Each conversation question has a prefix 'Q:' followed by answer prefix 'A:'. The final followup question has a prefix 'FOLLOWUP_Q:'.

[EX Q]: CONTEXT: Short answer: No.Long answer: this could probably be made to work, but only for a short time. At some point, and probably within a few uses, the rapid heat cycling from the fire would cause the pizza stone to crack.Pizza stones are made from corderite or clay, sometimes with grog. This offers a smoother surface than firebrick, but that smooth surface is because of a higher amount of vitrification and less airspace in the ceramic. This means they are less resistant to cracking due thermal shock, and the fact that your pizza stone is 1/4 a thick as firebrick makes that worse.In contrast, firebrick is a standard 2.5" thick, and made from higher-temperature materials with more airspace in the clay itself. These properties give it both higher thermal insulation, and higher thermal mass (so that it cools down slower). Both of these properties help it resist cracking.  <sep>  Q: Pizza stone as floor pizza oven vs firebrick A: This offers a smoother surface than firebrick  Q: Does it get as hot as firebrick? A: the fact that your pizza stone is 1/4 a thick as firebrick makes that worse  Q: Are there any advantages to using pizza stone? A: offers a smoother surface  Q: Is there an advantage to firebrick? A: both higher thermal insulation, and higher thermal mass  <sep> FOLLOWUP_Q: Ok, is there anything else you can add to help me with my decision?
[EX A]: the rapid heat cycling from the fire would cause the pizza stone to crack

[EX Q]: CONTEXT: Flour (+ water, either directly or from other ingredients such as egg white) gives the pastry structure. As you knead the flour, the gluten network develops and results in elasticity. When cooked, water evaporates from the dough leaving a rigid gluten skeleton. Fat does not mix with water and thus stay in blobs in between the gluten network. This weakens the gluten structure, making the pastry crumble.For this reason, you often see in recipes for shortcrust to avoid overmixing the fat. Buttery biscuits such as shortbread crumble more than crackers, which have more water. The same rationale applies to puff pastry. The thin fat layers are impermeable, so water steam gets trapped and exercise pressure upwards, lifting the pastry up.Quoting @GdD in the comments, the punchline is:more fat = crumblier, less fat has more structure.  <sep>  Q: How does altering the fat-to-flour ratio affect the pastry? A: more fat = crumblier, less fat has more structure  <sep> FOLLOWUP_Q: Is it only crumblier after it bakes?
[EX A]: The thin fat layers are impermeable, so water steam gets trapped and exercise pressure upwards, lifting the pastry up

[EX Q]: CONTEXT: There is some difference between the flavor, but seeing as there are so many other predominant flavors in Worcestershire sauce and that fact that you're (hopefully) not drinking it straight, it's fairly insignificant. It's very common for one product produced in different countries to have a range of manufacturing differences, sometimes arbitrary, sometimes to suit the local palate, and sometimes because of costs, hence people calling American Lea & Perrins a "knockoff."I've had both, and can assure you that once you've mixed it into a casserole or marinade you won't really miss anything. If you're striving for needlessly authentic British flavor you could always add a little malt vinegar to whatever you're cooking!  <sep>  Q: Is there a difference between US Worcestershire sauce and UK Worcestershire sauce? A: There is some difference between the flavor  <sep> FOLLOWUP_Q: What is the difference in flavor?
[EX A]:
it's fairly insignificant
