Input: Wood
The structure of hardwoods is more complex. The water conducting capability is mostly taken care of by vessels: in some cases (oak, chestnut, ash) these are quite large and distinct, in others (buckeye, poplar, willow) too small to be seen without a hand lens. In discussing such woods it is customary to divide them into two large classes, ring-porous and diffuse-porous.

In wood from a willow tree, what would you need to use to see the tiny vessels?
Output: a hand lens

Input: Article: In the shrinking PC industry, Dell continued to lose market share, as it dropped below Lenovo in 2011 to fall to number three in the world. Dell and fellow American contemporary Hewlett Packard came under pressure from Asian PC manufacturers Lenovo, Asus, and Acer, all of which had lower production costs and willing to accept lower profit margins. In addition, while the Asian PC vendors had been improving their quality and design, for instance Lenovo's ThinkPad series was winning corporate customers away from Dell's laptops, Dell's customer service and reputation had been slipping. Dell remained the second-most profitable PC vendor, as it took 13 percent of operating profits in the PC industry during Q4 2012, behind Apple Inc.'s Macintosh that took 45 percent, seven percent at Hewlett Packard, six percent at Lenovo and Asus, and one percent for Acer.

Now answer this question: What other American company fell behind Lenovo with Dell?

Output: Hewlett Packard

Article: The Sumerians were a non-Semitic caucasoid people, and spoke a language isolate; a number of linguists believed they could detect a substrate language beneath Sumerian, because names of some of Sumer's major cities are not Sumerian, revealing influences of earlier inhabitants. However, the archaeological record shows clear uninterrupted cultural continuity from the time of the early Ubaid period (5300 4700 BC C-14) settlements in southern Mesopotamia. The Sumerian people who settled here farmed the lands in this region that were made fertile by silt deposited by the Tigris and the Euphrates rivers.

Question: When were settlements started in southern Mesopotamia?
Ans: early Ubaid period

Here is a question about this article: Title I of the U.S. DMCA, the WIPO Copyright and Performances and Phonograms Treaties Implementation Act has provisions that prevent persons from "circumvent[ing] a technological measure that effectively controls access to a work". Thus if a distributor of copyrighted works has some kind of software, dongle or password access device installed in instances of the work, any attempt to bypass such a copy protection scheme may be actionable though the US Copyright Office is currently reviewing anticircumvention rulemaking under DMCA anticircumvention exemptions that have been in place under the DMCA include those in software designed to filter websites that are generally seen to be inefficient (child safety and public library website filtering software) and the circumvention of copy protection mechanisms that have malfunctioned, have caused the instance of the work to become inoperable or which are no longer supported by their manufacturers.
What is the answer to this question: Anticircumvention exemptions are generally seen to be be what?
****
So... inefficient

The problem: Answer a question about this article:
The ability of birds to navigate during migrations cannot be fully explained by endogenous programming, even with the help of responses to environmental cues. The ability to successfully perform long-distance migrations can probably only be fully explained with an accounting for the cognitive ability of the birds to recognize habitats and form mental maps. Satellite tracking of day migrating raptors such as ospreys and honey buzzards has shown that older individuals are better at making corrections for wind drift.
What are examples of day migrating raptors?
****
The answer: ospreys and honey buzzards
