In the Rig-Veda, Agni is connected with:

Concept — A passage-based comprehension item is settled by what the passage itself asserts, never by outside scholarship on the subject. The reliable method is to locate the sentence in which the term named in the stem is itself the grammatical subject of a stated relation, and then read off the complement of that relation. Distractors in such items are usually drawn from the same passage, but they belong there to some other subject, and they are often reworded rather than quoted.

Application — The passage sets up a two-factor scheme — karma and jñāna — and attaches each element it mentions to one level of that scheme:

• Karma is connected with the world immediately above the one in which we live.

• Jñāna is connected with the world further above that, and it is only through jñāna that the soul reaches a state of everlasting bliss.

• Agni and Indra are connected with sacrifices, while the gods of the highest world are connected with prayer and jñāna.

The stem names Agni. In the passage Agni is the grammatical subject of just one stated relation — “Agni and Indra are connected with sacrifices.” The complement of that relation, and therefore the answer, is sacrifices.

Cross-check — The passage supplies a referent for each of the other offered descriptions too, and in every case that referent is something other than Agni. Two of those descriptions are reworded rather than quoted, so match them to the passage by sense, not by wording:

The reading is confirmed by the passage’s next step: because the Vedic Samhitās are intimately connected with sacrifices, the sacrificial gods of the two lower regions — Agni among them — are the more prominent deities of the Rig-Veda. Hence, in the Rig-Veda, Agni is connected with sacrifices.
