1. RED CABBAGE
2. BLINDNESS
3. pH VALUE
ANSWERS ABOVE ARE MORE ACCURATE, SINCE PLANT IS MORE GENERAL THAN RED CABBAGE, BLINDNESS <NOUN> IS MORE SERIOUS THAN IRRITATION SINCE THE SULPHURIC ACID IS CONCENTRATE, NOT DILUTE, PAY ATTEENTION TO THE WORD pH, WHICH <p> IS A SMAILL CAPITAL LETTER, SOME SIRS AT SCHOOL MUST DEDUCT MARKS THERE.
SO, SOMEONE GOT 4A EVEN IN A-LEVEL CHEM / BIO DOES NOT MEAN HE / SHE CAN TEACH WELL.
