Here is a question about this article: From 1525 to 1917 14,503 titles were published in Estonian, as opposed to the 23,868 titles which were published between 1918 and 1940.[citation needed]
What is the answer to this question: In the years between 1918 and 1940 how many Estonian language books were printed?
****
So... 23,868

Here is a question about this article: Notably, a statute does not disappear automatically merely because it has been found unconstitutional; it must be deleted by a subsequent statute. Many federal and state statutes have remained on the books for decades after they were ruled to be unconstitutional. However, under the principle of stare decisis, no sensible lower court will enforce an unconstitutional statute, and any court that does so will be reversed by the Supreme Court. Conversely, any court that refuses to enforce a constitutional statute (where such constitutionality has been expressly established in prior cases) will risk reversal by the Supreme Court.
What is the answer to this question: What must happen to a statute for it to become unconstitutional?
****
So... it must be deleted

Here is a question about this article: Stepper motors can be rotated to a specific angle in discrete steps with ease, and hence stepper motors are used for read/write head positioning in computer floppy diskette drives. They were used for the same purpose in pre-gigabyte era computer disk drives, where the precision and speed they offered was adequate for the correct positioning of the read/write head of a hard disk drive. As drive density increased, the precision and speed limitations of stepper motors made them obsolete for hard drivesthe precision limitation made them unusable, and the speed limitation made them uncompetitivethus newer hard disk drives use voice coil-based head actuator systems. (The term "voice coil" in this connection is historic; it refers to the structure in a typical (cone type) loudspeaker. This structure was used for a while to position the heads. Modern drives have a pivoted coil mount; the coil swings back and forth, something like a blade of a rotating fan. Nevertheless, like a voice coil, modern actuator coil conductors (the magnet wire) move perpendicular to the magnetic lines of force.)
What is the answer to this question: What do newer computer drives use instead of stepper motors?
****
So...
voice coil-based head actuator systems
