The Indus Valley Civilization was NOT confined to just Harappa and Mohenjodaro; it spanned over 1,500 sites across a vast region including Kalibangan, Rakhigarhi, Dholavira, Lothal, and many others. The other statements are correct: Harappans had great artistic sense, the Pipal tree was significant in their religion, and Mohenjodaro had the famous Great Bath.
