Ive searched it up for you! As it says by definition its the systematic study of the nature and behaviour of the material and physical universe, based on observation, experiment, and measurement, and the formulation of laws to describe these facts in general terms
Choices 2 and 5 are correct. The other sentences use too many commas and periods in the wrong placements. If you read it out and pause at each comma and period, the others will sound wrong to the ear. Hope this helps! :)
In the sentence pattern for asking questions, the subject is placed immediately after the operator (Operator [did, does, was] + Subject) while in the sentence pattern for making statements, the subject is placed before the verb phrase (Subject + VP). However, some statements may be in question form (You've already eaten?) and some questions (such as rhetorical ones) may be in statement form (Haven't you peed already?).

Answer: E) My mother considered the idea of a child sleeping alone a cruel American practice.
This sentence shows that the mother had a cultural background that was different from the American one. Even though for most Americans, a child sleeping alone would be common, for her it was a cruel practice. The excerpt shows that Hema's mother does not endorse all American practices, which indicates she has a different cultural heritage, in this case, a Bengali one.
