I found the paper out of format, but still not that challenging. The first (effect of temperature on sex of lizard eggs) question could be related to the Brine Shrimp practical. The second (sugar content of different varieties of apple) question was quite good. Way of constructing the table was a bit challenging at first but once you figured it out, the rest of the question untangled. I found the last question (effect of differing frequencies of yoga on increasing vital capcity) quite easy. The independent variable was (in my opinion of course) the frequency of yoga course attendence in times per week, and the dependent variable was the percentage increase in vital capacity after 3 months.
