Answer: 11 feet shorter than it’s mother.
Explanation:
Key phrase, “Two years ago, a baby elephant was 11 feet shorter than it’s mother”. Saying the only reference as if 2 years, being 11 ft shorter. As well as there being no starting unit to work from to reference fire but the animals actually are, thus therefore a trick question. It never tells you what their size is, only unnecessary extra info without giving a starting unit for reference. Or to put it simply, it only refers to to what it was and has became, and doesn’t refer to what it ever is.
