Based on the choices, you know that there will be a conjunction between the clauses of the first and second blanks. The contrast of “ancient times” and “recently” tells you to predict a word for the first blank that suggests contrast, which eliminates choices (A) because and (B) since, leaving you with answer choice (C) although. You know St. Elmo’s fire has been documented for a long time, so discount choice (E) reported for the second blank. Choice (D) may be tempting, because incinerated is related to fire, but it does not make sense in this sentence. That leaves (F) understood, which does make sense as a contrast with the phenomenon’s having been documented.
