Read the passage and answer the following questions:
Salt, a ubiquitous yet often underappreciated mineral, manifests in myriad forms, each possessin distinctive characteristics shaped by geological provenance and processing methods. Common table salt, the most prevalent variety, undergoes extensive refinement, wherein impurities are eliminated and iodine is often infused to combat endemic deficiencies. Its crystalline uniformity and rapid solubility make it indispensable in both culinary and industrial contexts. In contrast, sea salt is derived through the gradual evaporation of seawater, a process that preserves trace minerals such as magnesium and potassium, thereby imparting subtle variations in flavour and hue. Gourmet enthusiasts often extol its coarse granules for the nuanced crunch they confer to dishes.
Himalayan pink salt, quarried from ancient seabeds in the Punjab region, owes its blush to iron oxide deposits. Advocates claim it offers health benefits beyond mere sodium intake, though empirical substantiation remains contested within scientific circles. Black salt, or kala namak, prevalent in South Asian gastronomy, emanates a sulphurous aroma attributable to its volcanic origins, lending complexity to traditional savouries.
'Fleur de sel', literally 'flower of salt,' represents the zenith of artisanal salt production, hand- harvested from the delicate crust forming on salt pans. Prized for its rarity and textural delicacy, it is more an embellishment than a staple seasoning. Thus, while chemically unified by their sodium chloride essence, salts diverge in sensory appeal, mineral composition, and cultural significance, rendering them as much a subject of connoisseurship as of necessity.
Identify the correct transformation of the sentence below into the passive voice without altering its meaning.
Original sentence from the passage:
'Gourmet enthusiasts often extol its coarse granules for the nuanced crunch they confer to dishes.'
Show answer & explanation
Correct answer: A
Explanation
To transform the sentence into passive voice, the object of the active sentence ('its coarse granules') becomes the subject of the passive sentence. The verb 'extol' is changed to its passive form ('are extolled') while maintaining the tense of the original sentence ('often extol' becomes 'are often extolled').
