Question 36

'Composed' means to consist of

In the context of the extract, 'composed' refers to the structure of a water molecule, indicating that it consists of one oxygen atom and two hydrogen atoms.

A) To consist of

This option accurately reflects the meaning of 'composed' as used in the extract. The sentence describes how water is made up of specific atoms, making 'to consist of' the correct interpretation.

B) To be uniquely discovered

This option is incorrect because 'composed' does not imply a discovery aspect. It refers to the makeup or structure of something rather than the process of finding or identifying it.

C) To be set apart

This option does not align with the meaning of 'composed.' Being 'set apart' suggests distinction or separation, which is unrelated to the composition or makeup of a substance like water.

D) To be surprised

This option is also incorrect, as 'to be surprised' has no connection to the scientific description of a molecule's structure. 'Composed' does not convey any emotional reaction but rather a factual statement about composition.

Conclusion

The choice 'to consist of' is definitively correct as it directly aligns with the explanation of water's molecular structure in the extract. All other options misinterpret the term 'composed,' focusing on unrelated meanings that do not fit the scientific context presented.
