Final answer:
The word that best matches 'glimmeringly' is 'weakly'.
Step-by-step explanation:
The word in italics is 'glimmeringly' which describes how the campfire is visible. To choose the best matching word or phrase from the options, we need to think about how the fire is described. 'Intermittently' means occurring at irregular intervals, which doesn't quite fit with the idea of visual visibility. 'Brightly' means with a strong, vivid light, which is not specified in the sentence. 'Weakly' means with little strength or force, which also does not match the description of the visible fire. The word that best matches 'glimmeringly' is 'O weakly' as it describes the fire as visible but with a faint, weak light.
