Here are some things to consider.
2 Nephi 9:41 says "the way for man is narrow." Compare that to other passages in the text that refer to narrow places, such as a narrow strip of wilderness, a narrow neck, a narrow neck of land, etc. Then consider various proposed maps of Book of Mormon geography and see how they interpret the term "narrow." The obvious anomaly is a "narrow neck of land" that is over 100 miles wide.
2 Nephi 9:53 says, "he has promised unto us that our seed shall not utterly be destroyed, according to the flesh, but that he would preserve them; and in future generations they shall become a righteous branch unto the house of Israel." Where do the scriptures say the descendants of Lehi live? Hint: See D&C 28, 30 and 32.
What land qualifies as the fulfillment of the following prophecy?
2 Nephi 10:10 But behold, this land, said God, shall be a land of thine inheritance, and the Gentiles shall be blessed upon the land.
11 And this land shall be a land of liberty unto the Gentiles, and there shall be no kings upon the land, who shall raise up unto the Gentiles.
12 And I will fortify this land against all other nations.
Last week I said I'd discuss 2 Nephi 5 later. Here are some of the main points, taken from chapter 11 of Moroni's America:
