Q:

Read the passage carefully and choose the best answer to each question out of the four alternatives.


Prebiotics are the lesser-known gut-health promoters which serve as food for good bacteria inside the gut. "We found that dietary prebiotics can improve non-REM (random eye movement) sleep, as well as REM sleep after a stressful event," said Robert Thompson, a PhD researcher at University of Colorado Boulder in the U.S. Prebiotics are dietary fibres found naturally in foods like artichokes, raw garlic, leeks and onions.

When beneficial bacteria digest prebiotic fibre, they not only multiply, improving overall gut health, but they also release metabolic by-products. Researchers fed three-week-old male rats a diet of either standard chow or chow that included prebiotics. They then monitored the rats' body temperature, gut bacteria and sleep-wake cycles — using electroencephalogram (EEG), or brain activity testing over time. Findings revealed that the rats on the prebiotic diet spent more time in non-rapid-eye-movement (NREM) sleep, which is restful and restorative, than those on the non-prebiotic diet.


How are metabolic by-products released?

A) When good bacteria help sleep B) When good bacteria digest dietary fibres
C) When gut becomes rich in nutrients D) After recovery from stress due to sleep
 
Answer & Explanation Answer: B) When good bacteria digest dietary fibres

A) Inspections B) Data flow analysis
C) Error guessing D) Walkthrough
 
Answer & Explanation Answer: C) Error guessing

Explanation:

Static Testing, a software testing technique in which the software is tested without executing the code. This Techniques provide a powerful way to improve the quality and productivity of software development by assisting engineers to recognize and fix their own defects early in the software development process.

 

It has two parts as listed below:

Review - Typically used to find and eliminate errors or ambiguities in documents such as requirements, design, test cases, etc.

Static analysis - The code written by developers are analysed (usually by tools) for structural defects that may lead to defects.

 

In this software is tested without executing the code by doing Review, Walk Through, Inspection or Analysis etc.

 

Hence, Error guessing is not a static software testing technique.
