Question: Unpopulated boards are usually bare-board tested for "shorts" and "opens". A short is a connection between two points that should not be connected. An open is a missing connection between points that should be connected. For high-volume production a fixture or a rigid needle adapter is used to make contact with copper lands on the board. Building the adapter is a significant fixed cost and is only economical for high-volume or high-value production. For small or medium volume production flying probe testers are used where test probes are moved over the board by an XY drive to make contact with the copper lands. The CAM system instructs the electrical tester to apply a voltage to each contact point as required and to check that this voltage appears on the appropriate contact points and only on these.

Question: Prizes are awarded on the results of trials (internal exams), GCSE and AS-levels. In addition, many subjects and activities have specially endowed prizes, several of which are awarded by visiting experts. The most prestigious is the Newcastle Scholarship, awarded on the strength of an examination, consisting of two papers in philosophical theology, moral theory and applied ethics. Also of note are the Gladstone Memorial Prize and the Coutts Prize, awarded on the results of trials and AS-level examinations in C; and the Huxley Prize, awarded for a project on a scientific subject. Other specialist prizes include the Newcastle Classical Prize; the Rosebery Exhibition for History; the Queen’s Prizes for French and German; the Duke of Newcastle’s Russian Prize; the Beddington Spanish Prize; the Strafford and Bowman Shakespeare Prizes; the Tomline and Russell Prizes in Mathematics; the Sotheby Prize for History of Art; the Waddington Prize for Theology and Philosophy; the Birley Prize for History; The Lower Boy Rosebery Prize and the Wilder Prize for Theology. Prizes are awarded too for excellence in such activities as painting, sculpture, ceramics, playing musical instruments, musical composition, declamation, silverwork, and design.

Question: The majority of simplified characters are drawn from conventional abbreviated forms, or ancient standard forms. For example, the orthodox character 來 lái ("come") was written with the structure 来 in the clerical script (隶书 / 隸書, lìshū) of the Han dynasty. This clerical form uses one fewer stroke, and was thus adopted as a simplified form. The character 雲 yún ("cloud") was written with the structure 云 in the oracle bone script of the Shang dynasty, and had remained in use later as a phonetic loan in the meaning of "to say" while the 雨 radical was added to differentiate meanings. The simplified form adopts the original structure.
Is there an answer to this question: What was written with the structure in the clerical script?

Answer:
orthodox character
