Implementation of https://github.com/jagilley/fact-checker. Works pretty well. <img width="993" alt="Screenshot 2022-12-07 at 4 41 47 PM" src="https://user-images.githubusercontent.com/101075607/206302751-356a19ff-d000-4798-9aee-9c38b7f532b9.png"> Verifying this manually: 1. "Only two kinds of egg-laying mammals are left on the planet today—the duck-billed platypus and the echidna, or spiny anteater." https://www.scientificamerican.com/article/extreme-monotremes/ 2. "An [Echidna] egg weighs 1.5 to 2 grams (0.05 to 0.07 oz)[[19]](https://en.wikipedia.org/wiki/Echidna#cite_note-19) and is about 1.4 centimetres (0.55 in) long." https://en.wikipedia.org/wiki/Echidna#:~:text=sleep%20is%20suppressed.-,Reproduction,a%20reptile%2Dlike%20egg%20tooth. 3. "A [platypus] lays one to three (usually two) small, leathery eggs (similar to those of reptiles), about 11 mm (7⁄16 in) in diameter and slightly rounder than bird eggs." https://en.wikipedia.org/wiki/Platypus#:~:text=It%20lays%20one%20to%20three,slightly%20rounder%20than%20bird%20eggs. 4. Therefore, an Echidna is the mammal that lays the biggest eggs. cc @hwchase17
