DISCUSSION: The fourth paragraph shows that the author is extremely skeptical of Temple’s theory.
There are more Calvaria major trees than Temple realized (fourth paragraph). The seeds can germinate without abrasion by bird gizzards (fourth paragraph).
The last sentence of the fourth paragraph does indicate that the author is not 100% certain Temple is wrong. The author says the decline in the tree ‘could easily be due’ to other factors. The author doesn’t say that other factors are definitely the cause.
- The fourth paragraph almost completely contradicts Temple’s theory.
- Same as A.
- Debatable. Temple’s theory is almost certainly wrong, so it’s hard to say it is a valuable theory.
- It’s not useful to have a precisely formulated theory if the theory is wrong. In the fourth paragraph, the author shows that they think Temple was wrong.
- CORRECT. See the fourth paragraph. Contrary to Temple’s ideas, there are many Calvaria major trees, and their seeds can germinate.
