The correct way to rewrite this sentence would be <em>by adding the word "then"</em>, which is <em>an adverb of time and a connector that expresses the continuity of time</em>, and also by making <em>the necessary changes</em>. The sentence describes <em>three stages of an elephant's life and how its tusks are in all three stages</em>. So, the sentence asks for a connector that can cause<em> the continuity effect, that can express a consequence in time</em>, meaning, "after that". Also, it is necessary to add <em>the personal pronoun "They"</em>, referring to <em>the subject "elephants"</em>, in order to make the verb<em> "to get" in the sentence become grammarly correct</em>. Moreover, the subject "Elephants" should be written <em>without the apostrophe</em>, because the<em> "s" </em>at the end of the word configures<em> plural, not possessive</em>. The corrected sentence would be:
Elephants are born without tusks, then they get baby tusks and replace those with adult tusks.
