Question 12

The islands have sharks, choppy currents, and a jagged coastline.

The author speculates that the combination of sharks, underwater currents, and jagged coastline contributed to the nickname "Devil's Teeth" for the Farallon Islands. This evidence directly links the dangerous natural features to the ominous name.

A) The islands have sharks, choppy currents, and a jagged coastline.

This option is correct as it directly reflects the evidence provided in the extract. The author mentions that the presence of sharks, underwater currents, and a jagged coastline are likely reasons for the nickname, establishing a clear connection between these elements and the daunting imagery of "Devil's Teeth."

B) Swimming from San Francisco to the islands is very challenging.

While this statement may be true, it does not directly address the reason behind the nickname "Devil's Teeth." The author does not use the challenge of swimming to explain the name, making this option incorrect.

C) In 1863, violence broke out on the islands during a historical event.

This option is irrelevant to the speculation regarding the nickname. The extract does not mention any historical events or violence as contributing factors to the name, thus rendering this choice incorrect.

D) They have always been called that by sailors who traveled past them.

This option suggests a historical naming convention but does not provide evidence or reasoning connected to the natural features that inspired the nickname. The extract does not support this claim, making it an incorrect choice.

Conclusion

The correct answer, A, is definitively right because it aligns with the evidence presented in the extract, linking the physical characteristics of the Farallon Islands to their nickname. All other options fail to provide relevant or supported reasoning as to why the islands are called "Devil's Teeth." Thus, they do not fulfill the criteria established by the author.
