Point 5 — The Case of “Though”
IC + though + IC — though as a strong transition. IC + though + IC + IC — though as a subordinating conjunction.
A. IC + though + IC (though as a strong transition):
- If a period or semicolon is available, choose it to avoid a run-on or comma splice.
- If not, choose colon or dash.
- Valid shapes: IC . / ; / : / — though , IC or IC , though . / ; / : / — IC.
B. IC + though + IC + IC (though as a subordinating conjunction): follow IC . / ; / : though IC , IC — that is, IC. DC, IC.

Recent analysis of 617 Patroclus—a binary Trojan asteroid orbiting the Sun in Jupiter’s gravitational zone—has confirmed its composition to be dark and carbon-rich, suggesting a primitive origin. Such interpretations are ultimately ______ the object’s dark surface coloring may result from exposure to radiation and micrometeorite impacts rather than from intrinsic compositional properties.
