  1. As half a physicist it was interesting to see how the physical aspect was described, and I learnt the basics of photosynthesis which was nice.

    I had a word I could not get:
    p2c1l13:    "? energy that is"

    And a few of questions:
    (a) is the first form on p3c1l3 "thingS"?
    (b) is the penultimate form on p3c2l11 "considering"?
    (c) should there be a "to" before humans on p4c2l22?; and on p5c2l9/10 should there be a "to" or "for" between "chemical" and "which"?  Maybe it was the author who foxed me.
    (d) p7c1l14:  is it "and thus we IDENTIFY"?

    1. Thanks for the corrections to pages 3 and 4. Here are the answers to your questions.

      p2c1l13: "inexhaustible"

      p3c2l11: "conceiving"

      p5c2l9-10: "chemical change"

      p7c1l14: Yes, the word is "identify."

  2. Thanks Carlos.  Some nice points. 

    I should have considered "conceive". 

    "Inexhastable":  The manual (para 106) had a rule to put in the vowel if a vowel followed the consonant.  And para 103 in the pre-anniversary says the same.  Only in Q&A (no. 81) does he explain about "compound prefixes" — which is a rather fine judgement to make I feel.

    I had a fixed idea of what I was reading and was not flexible enough to read "change" rather than "which".

    "Identify":  It was obvious when reading it (after I had decided it was "Ident…").  Looking at my dictionary the endings for that word seem rather random — I cannot place them into a similar group of "word families".
