What is the test for a motion requiring defendants to file an answer?

Taken together and liberally construed, these allegations are sufficient to warrant ordering [Defendants] to file an answer because they survive the low threshold required to plead a plausible claim for relief under the Eighth Amendment. See 28 U.S.C. 1915A(b); Wilhelm v. Rotman, 680 F.3d 1113, 1116, 1121, 1123 (9th Cir. 2012) (noting that screening pursuant to 1915A incorporates the familiar standard applied in the context of failure to state a claim under Federal Rule of Civil Procedure 12(b)(6).).
