Cause, Effect, and Addition: Three Arrows That Look Alike

Every transition question is really two claim boxes joined by one arrow. Box one holds a fact, box two holds another fact, and the word you choose announces what kind of arrow connects them. 'So' and 'and' can sit between the exact same two facts and still mean different things, because 'so' asserts that box one produced box two, while 'and' only asserts that both boxes exist. The facts never change. The claim about their relationship does.

A cause arrow, like thus, as a result, or consequently, is a promise: the writer is telling you the first event is the reason the second one happened. That promise has to be earned by the content, not just assumed from timing. Two events can occur one after another with zero causal link between them, which is exactly when an addition arrow, like in addition, also, or furthermore, is the honest choice, because addition only reports that both things happened and refuses to guess why. Order on the page is not evidence of cause. You need the sentence to show a mechanism, a condition, or a result before thus is earned.

This matters most when the sentence flips the usual order and gives the effect first. A connector like because, since, or due to can still point backward to a cause even when that cause arrives second, so the arrow's direction is about logic, not position in the sentence. This is the same skill tested throughout the unit: find what the two claim boxes actually assert about each other, then let that relationship, not habit or word length, choose the transition.
