Passage

The okapi, a forest mammal of central Africa, has presented zoologists with a number of difficult questions since they first learned of its existence in 1900. The first was how to classify it. Because it was horse like in dimension, and bore patches of striped hide similar to a zebra’s (a relative family is confirmed by its skin-covered horns (in males), two-lobed canine teeth, and long prehensile tongue.

The next question was the size of the okapi population. Because okapis were infrequently captured by hunters, some zoologists believed that they were rare; however, others theorized that their habits simply kept them out of sight. It was not until 1985, when zoologists started tracking okapis by affixing collars equipped with radio is concentrated in an extremely limited chain of forestland in northeastern central Africa, surrounded by savanna.

One reason for their seeming scarcity is that their coloration allows okapis to camouflage themselves even at close range. Another is that okapis do not travel in groups or with other large forest mammals, and neither frequent open riverbanks nor forage at the borders of clearings, choosing instead to keep to the and because of the distribution of their food, okapis engage in individual rather than congregated foraging.

But other questions about okapi behavior arise. Why for example, do they prefer to remain within forested areas when many of their favorite plants are found in the open border between forest and savanna? One possibility is that this is a defense against predators; another is that the okapi was pushed into and that they continue to respect those borders even though available forestland has long since expanded.

What this question is testing

Main Point

Your task

Capture the passage's overall primary point — the claim everything else supports.

Common trap

Answers that are true but too narrow (a single paragraph) or too broad (beyond the passage's scope).

Winning move

Summarize the whole passage in one sentence first, then match it to a choice.

The question
1.

Which one of the following most completely and accurately expresses the main idea

Answer choices

  1. Too Narrow4% picked this

    Information gathered by means of radio-tracking collars has finally provided answers to the questions about okapis that zoologists have been attempting to answer since

    This relates to the 2nd paragraph, but it accuses the passage of conveying a vibe like, "Now that we've got these collars, we've got all the answers we were looking for!" The last paragraph is specifically reminding us that there are many unanswered questions.

  2. Too Specific: start of 20th7% picked this

    Because of their physical characteristics and their infrequent capture by hunters, okapis presented zoologists with many difficult questions at the

    This answer is somewhat tempting. The main clause reflects the overarching idea we're looking for ("we've got a lot of questions about the okapi"). The causal reasons provided in the warm-up clause are indeed relevant factors. But they aren't all of the relevant factors (for example, the fact that they feed almost entirely on leaves and don't travel in groups also contribute to their elusiveness), and there's no reason in the passage to elevate the two causal factors that are mentioned. However perhaps the easiest, though pettiest, way to disqualify this answer is that it says the difficult questions happened at the beginning of the 20th century, the early 1900s'. Our thesis says, "since we discovered the okapi in the early 1900s we've had lots of questions", but that doesn't mean that all our important questions happened in the early 1900s.

  3. Correct83% picked this

    Research concerning okapis has answered some of the questions that have puzzled zoologists since their discovery, but has also raised other questions regarding

    Why this is right

    This looks like the overarching Theme we want (i.e. "we've got questions about the okapi"). And it nicely captures how some of the questions presented in the passage had answers, while others didn't.

    Skill tested: Main Point · how this choice captures the passage's function is the move to repeat next time.

  4. Too Narrow3% picked this

    A new way of tracking okapis using radio-tracking collars reveals that their apparent scarcity is actually a result of their coloration, their

    This doesn't sound anything like our big-picture idea, which is about having lots of questions about the okapi. This sounds more like what you'd say the Main Point was, if you had only read paragraphs 2 and 3. But this answer, like (A), conveys too much of a "now our confusion is resolved" type feel. Meanwhile, the passage itself made sure that the final taste in our mouth was "there's still a lot we don't know".

  5. Too Strong: mostly3% picked this

    Despite new research involving radio tracking, the questions that have puzzled zoologists about okapis since their discovery at the start of the

    This has the right big picture focus (on "questions about okapi"), but it comes off overly negative. It's saying, "Despite some progress, we're still mostly in the dark". The passage felt more like, "We've made some progress! (Although in some areas we're still in the dark)" When we check on the wording that starts the final paragraph, we can't find support for the idea that questions are mostly unanswered. It just says "other questions arise".
