Understanding Exact Duplicates: A Look at the Wonderlic Cognitive Ability Test

    Ever stumbled upon a tricky question that makes you scratch your head a bit? You know the type—those questions that require you to pick apart details with the precision of a watchmaker. One typical question you might encounter in tests like the Wonderlic Cognitive Ability Test revolves around identifying exact duplicates. Let’s take a closer look at how to approach a question like, “How many of the five pairs listed below are exact duplicates: 6845-6845, 45641-45641, 987878-987788, 124555-123555, 9898547-9898745?”

    Now, here’s the gist: The first step is to analyze each pair carefully. Think of it as a mini detective mission. You don’t want to overlook the smallest detail, because, honestly, that’s where the magic—or the mistakes—often happen.

    Let’s break it down. The first pair, **6845-6845**, is a straightforward win—identical numbers! This one definitely counts as a duplicate. It’s like finding a matching sock—you’re 100% sure they belong together.

    Moving on to the second pair, **45641-45641**. Just like our first example, these numbers don’t stray one bit. You’ve got another duplicate on your hands! You can almost hear a cheer, can’t you? 

    But hold on! Here comes the plot twist with the third pair, **987878-987788**. Now, if you squint, you might think they’re similar, but are they? Nope! They differ in the last two digits. That’s a game-changer. This pair doesn't make the cut.

    Let’s keep rolling. The fourth pair, **124555-123555**, presents yet another difference in the middle digits. We’re looking for duplicates here, and those digits are simply too different. So, we can strike another pair off our list.

    Lastly, we arrive at **9898547-9898745**. At first glance, they might seem alike, but take a second look. The sequences differ enough to consider them unique. So, no duplicate award here. 

    Based on our detailed analysis, only two pairs—**6845-6845** and **45641-45641**—are confirmed duplicates. So, the answer to our original question is two. That’s right—two pairs! Understanding how to dissect these questions not only sharpens your cognitive skills but also builds your confidence for test day.

    Now, don’t forget—questions about duplicates are just one little piece of the Wonderlic puzzle. It’s worth remembering that preparation is key. Try out practice tests, familiarize yourself with the structure, and keep honing those analytical skills. You know what they say, practice makes perfect!

    So next time you face a question on duplicates, remember this little breakdown. With patience and a sharp eye, you’ll conquer that question—and many others—like a pro. Happy studying!
