Question 1 Report
| row | deficiency disease | substance lacking |
|---|---|---|
| 1 | scurvy | iron |
| 2 | rickets | vitamin C |
| 3 | anaemia | iron |
| 4 | constipation | calcium |
The table lists four deficiency diseases together with the substance said to be missing from the diet. Which row is correct?
Answer Details
Anaemia is caused by a shortage of iron, so the row pairing anaemia with iron is the correct match. The other rows are wrong: scurvy is caused by a lack of vitamin C (not iron), rickets by a lack of vitamin D or calcium (not vitamin C), and constipation by a lack of fibre (not calcium). Learning each deficiency with its specific missing substance lets you reject the mismatched rows and select the anaemia-iron pairing.
