Analyzing Blank Number 2 in the Passage

The phrase around blank number 2 is "are helpful (2) ______ warding off osteoporosis". We need a word that connects the state of being "helpful" with the action "warding off osteoporosis". The action "warding off osteoporosis" describes the area or purpose for which calcium supplements are helpful.

Let's look at the options provided for blank number 2:

1. in
2. by
3. out
4. into

Evaluating the Options for Blank 2

Let's consider each option in the context of the phrase "helpful ______ warding off osteoporosis".

Evaluating Option 1: 'in'

If we use 'in', the phrase becomes "helpful in warding off osteoporosis". The preposition 'in' is often used to indicate the area, field, or activity in which someone or something is helpful. For example, "She is helpful in solving math problems." or "The tool is helpful in repairing the car." This structure makes grammatical sense and fits the meaning that calcium supplements assist in the process of preventing osteoporosis.

Evaluating Option 2: 'by'

If we use 'by', the phrase becomes "helpful by warding off osteoporosis". The preposition 'by' is usually used to indicate the means or method by which something is done. While "warding off osteoporosis" is the outcome, the phrasing "helpful by warding off" is not standard English construction in this context. We might say "They ward off osteoporosis by taking calcium supplements," but not typically "supplements are helpful by warding off".

Evaluating Option 3: 'out'

If we use 'out', the phrase becomes "helpful out warding off osteoporosis". 'Out' is a versatile word but does not form a standard phrase with 'helpful' in this context. Phrases like "help out" mean to assist someone, but this doesn't fit the structure "helpful out [doing something]".

Evaluating Option 4: 'into'

If we use 'into', the phrase becomes "helpful into warding off osteoporosis". The preposition 'into' usually indicates movement or transformation. It does not fit grammatically or semantically with "helpful" in this phrase describing the purpose or area of help.

Why 'in' is the Most Appropriate Choice for Blank 2

Comparing the options, the phrase "helpful in warding off osteoporosis" is the only one that is grammatically correct and conveys the intended meaning. The preposition 'in' correctly indicates the activity or process (warding off osteoporosis) where the calcium supplements provide help.

Revision Table: Common Preposition Uses with 'Helpful'

Here's a look at how 'helpful' is commonly used with prepositions:

In our passage, "warding off osteoporosis" is an activity/process, making 'in' the most suitable preposition.

Additional Information: Using 'Helpful' with Different Structures

The word 'helpful' can be followed by different prepositions or structures depending on the context. When followed by an activity expressed as a gerund (like 'warding off'), 'in' is commonly used to specify the domain of help. For example, "These tips are helpful in reducing stress." or "The software is helpful in managing data." This reinforces why 'in' is the correct choice for blank 2 in the given passage about calcium supplements and osteoporosis.
