In the following question, the sentence given with a blank is to be filled in with an appropriate word. Select the correct alternative out of the four.If immigrants don't learn to speak the native languages of their new countries, they won't be able to ______ themselves into society.

The sentence discusses immigrants becoming a part of a new society.Integrate means to mix with and join society or a group of people, often combining to form a whole. It fits perfectly with the reflexive pronoun "themselves" followed by "into".Conjoin means to join together, typically used for physical objects.Interface means to interact with a system or person, but doesn't convey blending into a culture or society completely.Reconciliate (more commonly 'reconcile') means to restore friendly relations, which doesn't fit the context.Thus, 'integrate' is the correct word choice.
