I want to know the answer to the following question:
The landmark, General Grant National Memorial, is also called what?
All the background I'm provided with is that "Historic sites under federal management on Manhattan Island include Castle Clinton National Monument; Federal Hall National Memorial; Theodore Roosevelt Birthplace National Historic Site; General Grant National Memorial ("Grant's Tomb"); African Burial Ground National Monument; and Hamilton Grange National Memorial.". Is that enough to answer the question?
Answer: yes
