Clean Up Abbreviations and Decades
Remove unnecessary punctuation from abbreviations and decades. Drop apostrophes from decades (1990s, not 1990’s). Remove periods from acronyms (NASA, not N.A.S.A.). These errors mark amateur work.
Incorrect (unnecessary punctuation):
<p>The company was founded in the 1990's.</p>
<p>She works at N.A.S.A. on A.I. projects.</p>Correct (clean abbreviations):
<p>The company was founded in the 1990s.</p>
<p>She works at NASA on AI projects.</p>Exception: lowercase abbreviations that could be misread as words ("e.g.", "i.e.", "a.m.", "p.m.") may keep periods for clarity.
