<details id="response-source"><summary id="response-source-summary">Read the complete selected source</summary><h2>The display-tray records</h2><p>Made-up practice record. A museum display compares water lost from matching trays over the same 30-minute interval, using the same taught mL reading procedure. Start amounts, place and tray type are matched. Different display labels name trays J, K and L; the source does not specify a cause for differences. The valid supplied lost-water values are J=10 mL, K=0 mL, L=5 mL. Tray M has no recorded value. Tray N spilled, so its value is invalid for this comparison. Another group&#x27;s matched record gives J=5 mL. These are invented supplied records, not measurements you made.</p><h2>Four questions</h2><ol><li>Make a table or columns for J, K and L. Keep the unit.</li></ol><ol start="2"><li>Which record is zero, which is missing, and which had a spill?</li></ol><ol start="3"><li>Compare the two J readings. What could you check next?</li></ol><ol start="4"><li>Can these records prove J always loses 10 mL?
