On January 8, 2027, Lessee demanded that Lessor replace the Premise's flooring, which had cracked and splintered in many locations.

Grading rubric
Criteria and grader verdict (showcase run)
States that Lessor cannot require Lessee to replace the floor coverings
FailEvidence: TEXT_RESPONSE begins, “**Yes.** Under the Lease, Lessor can require Lessee to replace/install new flooring at Lessee’s expense.” Assessment: The criterion requires stating “Lessor cannot require Lessee to replace the floor coverings.” The response states the opposite, so fail.
States that Lessee is obligated to "maintain" the floor coverings
PassEvidence: TEXT_RESPONSE says Section 6.C requires Lessee to “maintain the Premises” and “expressly includes ‘floor coverings’ among the interior items for which Lessee is responsible.” Assessment: The criterion requires stating Lessee is obligated to “maintain” the floor coverings. This is clearly stated, so pass.
States that Lessee is obligated to pay for "required repairs or replacement."
PassEvidence: TEXT_RESPONSE quotes, “If Lessee fails to promptly make required repairs or replacements... Lessee shall repay the cost thereof...” Assessment: The criterion requires stating Lessee is obligated to pay for “required repairs or replacement.” The response conveys that Lessee must repay/pay those costs, so pass.
States that replacement of the floor coverings is not explicitly "required" by the Lease
FailEvidence: TEXT_RESPONSE says Lessor can require replacement “assuming the cracked and splintered flooring is a required repair or replacement” and concludes “Lessor may require Lessee to do so at Lessee’s expense.” Assessment: The criterion requires stating replacement of floor coverings is not explicitly “required” by the Lease. The response does not state this; it treats replacement as potentially/actually required. Fail.
States that the Lessor is prohibited from implying replacement obligation into the language of the Lease
FailEvidence: TEXT_RESPONSE concludes, “the better reading is: Lessor does not have to replace the flooring for Lessee; Lessor may require Lessee to do so at Lessee’s expense.” Assessment: The criterion requires stating Lessor is prohibited from implying a replacement obligation into the Lease language. The response does not mention such a prohibition and reaches the contrary conclusion. Fail.
