Answer:
The judge asked the lawyer if he would be able to complete his arguments tomorrow.
Step-by-step explanation:
An indirect speech is also known as "reported speech." This type of speech doesn't quote what was stated in the sentence; rather it tries to report.
The example sentence above is a "direct speech" which is supposed to be turned into a reported speech, which should include an indirect question (Will you be able to complete your arguments tomorrow?) In order to do this, "will" should be replaced with "would." The change in tenses largely depends on the mood. In this case, it is already stating something that happened in the past.
