Based on the contextual information provided about the regency era and excerpt from Jane pride and prejudice, why is mrs. Bennett eager for one of her daughters to marry the new neighbor

Women during that time relied on men to sustain their family, so daughters were commonly married off quickly to a man that looked as if he could provide for his wife and (eventual) family. Mrs. Bennett is eager to marry off her daughter because Mr. Bennet has died and she needs to marry one of her daughters off to ensure she is taken care of by her daughter's husband. I hope I explained this right!
