Summarize why Earth’s moon and Mercury have (and had) virtually no chance of hosting life. Use your own words. Adopt quantitative
reasoning (i.e., usage of numbers), if appropriate based on the subject. No copy-and-paste from the text book, internet or PDF (as previously supplied as study material) permitted, however. If you take material from other sources, use direct quotes (placed in “...”). However, sentences dominantly or solely existing out of quotes will not be counted as part of the 10 middle-long meaningful sentences.
