I disagree that this survey, we need not only a year and two years, but we need to explore the opinions of every grade, in order to know the precise opinion than to remove just one year and two years.
I am of the opinion that the surveys we have not only made one and two years but we need to explore the opinions of all ages, in order to understand more clearly that it took just one year and two years.
I am of the opinion that this survey, we must not only the year 1 and 2, but we need to survey the opinions of all the students to know the ideas more clearly than to just the year 1 and 2
