I doubt that they will "llegar" trade.
The correct verb to complete the sentence would be "sacar."
Here's a breakdown of the sentence: - "Dudo que ellos" means "I doubt that they." - "Trade" refers to the action being doubted. - "Sacar" means "to take out" or "to withdraw." - "Llegar" means "to arrive."
Based on the context, it seems like "sacar" is the most appropriate verb to use in this sentence. It would mean "I doubt that they will take out/withdraw trade."
If "llegar" were used instead, the sentence would mean "I doubt that they will arrive trade," which doesn't make sense in this context.
Remember, it's important to choose the correct verb that makes sense in the sentence and matches the intended meaning.
