Final answer:
The provided excerpts do not contain sufficient information to determine whether Uncle Jack approves of Tyndale's lessons with Tom in the book 'The Hawk That Dare Not Hunt by Day'.
Step-by-step explanation:
The question refers to the book The Hawk That Dare Not Hunt by Day. However, the provided excerpts do not contain information regarding Uncle Jack's approval or disapproval of Tyndale's lessons with Tom. In fact, none of the excerpts mention Uncle Jack or Tyndale at all or provide context related to their beliefs or actions concerning Tom's education. Therefore, it is not possible to determine the truthfulness of the statement without additional context from the book. For an accurate response to whether Uncle Jack approves of Tyndale's lessons with Tom, one would need to reference the specific part of the book where Uncle Jack's opinion is mentioned.
