The answer is technical reasoning: technical reasoning is the learning pattern that can help ensure that your points are concise (brief: using few words) and succinct. Unlike precision, which is the learning pattern that uses a lot/most words, technical reasoning uses the fewest words—it's concise and succinct, and can help people to think without depending too much on words.
The first is an armed head, summoned to warn Macbeth that Macduff is coming back to Scotland to ruin him. The second apparition is a bloody child and it tells Macbeth that no man born of a woman can do him harm. This gives Macbeth great confidence: "Then live Macduff: what need I fear of thee?" (4.1.78-80). The third apparition is that of a child wearing a crown and holding a tree. It declares:
Macbeth shall never vanquish'd be until
Great Birnam wood to high Dunsinane hill
<span>Shall come against him (4.1.87-90). </span>
<span>Macbeth is sure that the third apparition's prophecy will never be, for 'who can impress the forest?' or 'bid the tree unfix his earth-bound roots?' (4.1.91-3). </span>
