The correct phrase is "harmful for one's health." The preposition "for" is grammatically acceptable when discussing what is affected by something harmful. Both "for" and "to" are used with "harmful" depending on whether the focus is on what suffers (for) or what receives the harm (to). In this context, "for" correctly identifies health as the affected aspect.

The correct phrase is "resistant to fire." When something can withstand or resist something, "to" is the appropriate preposition showing what is being resisted. "For" would show purpose, "in" would show containment, and "on" would show surface contact.

The correct phrase is "aware of the risks." When someone has knowledge or consciousness of something, "of" is the standard preposition. "With" would show accompaniment, "at" would show location, and "on" would show surface contact.

The correct phrase is "accessible to members only." When something can be reached or used by someone, "to" is the appropriate preposition showing who can gain access. "With" would show accompaniment, "by" would show the agent, and "for" would show purpose or benefit.

The correct phrase is "satisfied with the management." When expressing contentment or approval about something, "with" is the standard preposition. "For" would show purpose, "to" would indicate direction, and "on" would show surface contact.

The correct phrase is "interested in animals." When someone wants to learn about or give attention to something, "in" is the appropriate preposition. "For" would show purpose or benefit, "on" would show surface contact, and "at" would show location.

The correct phrase is "overjoyed at the news." When describing extreme happiness caused by something, "at" is commonly used to show what triggered the emotion. "To" would indicate direction, "in" would show containment, and "on" would show surface contact.

The phrase 'qualified for' is the standard preposition combination in English. When someone has qualifications exceeding what a job requires, we say they are 'over-qualified for' that position. 'To', 'in', and 'on' do not collocate with 'qualified' in this context.

'Suspicious of' is the correct preposition collocation. When someone has doubts or mistrust about something or someone, we use 'of'. For example: suspicious of strangers, suspicious of his motives. 'To', 'at', and 'on' are not used with 'suspicious'.

'Pleased with' is the correct usage when expressing satisfaction about something. While 'pleased of' exists in limited contexts (like 'pleased with himself'), 'pleased with' is standard for results, news, or outcomes. 'By' and 'at' do not collocate with 'pleased'.

'Proud of' is the standard preposition combination. When expressing pride or satisfaction about achievements, possessions, or people, we use 'of'. For example: proud of my children, proud of our country. 'For', 'at', and 'to' are not correct with 'proud'.

'Essential to' is correct when describing something necessary or crucial for a person or purpose. Both 'essential to' and 'essential for' are acceptable, but 'essential to' is commonly used in this context. Knowledge of mathematics is indispensable for an engineer's work.

This adline follows the famous Mastercard 'Priceless' campaign format: 'There are some things money can't buy. For everything else, there's Mastercard.' The blank refers to Mastercard.

The subject 'schedule' is third-person singular, so it requires the singular verb form 'bewilders'. 'Bewilder' is the base form used with I/you/we/they, while 'bewildrers' and 'bewildur' are misspelled non-words. The sentence describes a recurring situation, so present tense is appropriate.

The subject 'Communication' is singular and uncountable, requiring the singular verb 'plays'. 'Played' is past tense, 'playing' is a participle, and 'played for' is grammatically incorrect. The sentence describes a general truth, so present tense is correct.
