Answer 1

1. b

The reason for that is mineral oil is used to treat constipation. It is known as a lubricant laxative. It works by keeping water in the stool and intestines. This helps to soften the stool and also makes it easier for stool to pass through the intestines.In this questions the word 'except' makes the stem word .

2. d

Combivent (ipratropium bromide and albuterol sulfate) is an inhaler that is a combination of an anticholinergic bronchodilator and a selective beta2-adrenergic agonist used to treat and prevent symptoms (wheezing and shortness of breath) caused by ongoing lung disease (chronic obstructive pulmonary disease-COPD .

3. d

Leukotriene receptor antagonists, such as montelukast, zafirlukast, and pranlukast, and 5-lipoxygenase inhibitors, like zileuton and Hypericum perforatum, can be used to treat these diseases. They are less effective than corticosteroids for treating asthma, but more effective for treating certain mast cell disorders.
