Answer:
She agrees that Oxen Meadows are really his.
Explanation:
"A Marriage Proposal" is a one-act play written by Anton Chekov. The play is about a marriage proposal that Lomov came with to Chubukov's house, his neighbour. Chubukov has a daughter named Natalya, a twenty-five-year-old girl.
When Lomov visits Chubukov's house, Lomov and Natalya get into an argument over the ownership of Oxen Meadows. And furious, Lomov leave the place but once the purpose of Lomov's visit is known to Natalya she gets into hysteric and persuades her father to bring Lomov back.
After Lomov came back Natalya agreed that the Oxen Meadows belong to him and not them she was mistaken because of confusion.
So, this is how she helped Lomov to fulfil his purpose.
