Class 7 English Poorvi Chapter 3 Conquering the Summit question answer
The correct version is: The guide insisted on a uniform jacket for the group’s safety during the trek. Although “uniform” starts with the vowel letter “u”, it begins with the consonant sound “yu”. In English, article choice depends on pronunciation. Since “uniform” starts with a consonant sound, the article “a” should be used instead of “an.” This correction follows the rule of using “a” before consonant sounds and “an” before vowel sounds.
