Emphasis Transitions

The question gives you two sentences and asks which connector logically joins them. Emphasis transitions fit when the second sentence is the first one turned up a notch: same claim, bigger evidence. 'In fact' and 'indeed' tell the reader: don't just add information, intensify what you already believe. That's why the right test is to ask what relationship the sentence pair actually has before you look at the answer choices. If sentence two proves sentence one harder than sentence one proved itself, you want emphasis.

Mechanically, 'indeed' and 'in fact' work by taking the claim in sentence one and supplying a more extreme instance or statistic that makes it undeniable. 'The drug helped most patients. In fact, it cured nine in ten' escalates: curing is a stronger outcome than merely helping, and 'nine in ten' sharpens 'most.' Compare that to 'moreover,' which would work if sentence two added a separate, parallel fact, like a second finding about side effects. Moreover adds; in fact intensifies the same point.

This is also why emphasis fails when sentence two narrows, qualifies, or contradicts sentence one. If a tidal barrage sentence praises reliable scheduling, then the next sentence says output has dropped at some sites, that's a limit on the claim, not a stronger version of it, so you need a restrictive phrase like 'in some instances,' not 'indeed.' On the test, this topic sits next to other connector types in the same question slot, so the real skill is sorting addition, contrast, cause, and restriction from true escalation before choosing.
