Who among the following invented the computer language COBOL?
Correct Answerसही उत्तर
A. Grace Murray HopperA. ग्रेस मरे हॉपर
Explanationव्याख्या
The printed solution selects Grace Murray Hopper.
However, the source explanation introduces an important qualification: it states that COBOL was designed in 1959 by CODASYL and was partly based on previous programming-language design work by Grace Hopper, who is commonly referred to as the '(grand)mother of COBOL'.
The book further says that COBOL was created as part of a United States Department of Defense effort to create a portable programming language for data processing.
Therefore the question wording, printed answer and explanatory text are not perfectly aligned.
The question asks who 'invented' COBOL and gives Grace Murray Hopper as the printed answer, while the explanation attributes the actual 1959 design to CODASYL and describes Grace Hopper's earlier work as an important basis.
In keeping with the source-preservation requirement, the answer remains index 0 because that is the book's printed solution, but the record is marked for review.
The source-supported facts are: COBOL — designed in 1959 by CODASYL; partly based on Grace Hopper's previous programming-language design work; Grace Hopper called the '(grand)mother of COBOL'; developed in connection with a US Department of Defense effort for a portable data-processing programming language.
John McCarthy, Guido van Rossum and Brendan Eich are distractors.
This entry should be independently reviewed before being used as a clean live quiz question.
Printed solution Grace Murray Hopper को सही उत्तर देती है। हालांकि source explanation एक महत्वपूर्ण qualification देती है। Book कहती है कि COBOL को 1959 में CODASYL द्वारा design किया गया था और यह Grace Hopper के previous programming-language design work पर partly based था। Grace Hopper को source '(grand)mother of COBOL' कहती है। Book आगे बताती है कि COBOL को United States Department of Defense के उस effort के हिस्से के रूप में बनाया गया था जिसका उद्देश्य data processing के लिए portable programming language तैयार करना था। इसलिए question wording, printed answer और explanation पूरी तरह aligned नहीं हैं। Question पूछता है कि COBOL का 'inventor' कौन था और printed solution Grace Murray Hopper देती है, जबकि explanation actual design को CODASYL से जोड़ती है और Grace Hopper के earlier work को महत्वपूर्ण आधार बताती है। Source को silently correct न करने की requirement के कारण answer index 0 preserve किया गया है, लेकिन record को review के लिए mark किया गया है। Source-supported facts हैं: COBOL — Designed in 1959 by CODASYL — Based Partly on Grace Hopper's Earlier Work — Grace Hopper = '(Grand)mother of COBOL' — US Department of Defense Effort — Portable Language for Data Processing। John McCarthy, Guido van Rossum और Brendan Eich distractors हैं। Live quiz में use करने से पहले इस question को independently review करना उचित होगा।
