Fill in the Blanks

Payment is based on the condition of delivery of goods....so, it is conditional.

Conscientious means showing great care and thoroughness in one's work, diligent and hard-working. In this context, it describes someone who is careful and diligent. Compulsory means mandatory, conditional means dependent, consecutive means successive, and condescending means patronizing.

Consecutive means following one after another in sequence, without interruption. In this context, it describes three days that follow each other in order. Conscientious means diligent, compulsory means mandatory, conditional means dependent, and condescending means patronizing.

Condescending remarks show a patronizing or superior attitude toward others, which naturally frustrates people and cause them to say 'I've had enough.' The other options don't fit - conscientious means careful/diligent, compulsory means required, conditional means dependent on something, and consecutive means following one after another.

Extensively means covering a wide area or thorough coverage, which is the standard collocation with travel. You travel extensively when you've been to many places. Essentially means fundamentally, easily means without difficulty, exactly means precisely, and especially means particularly - none fit the travel context as well.

Eminently means very or extremely, and 'eminently suitable' is a standard phrase meaning very well-suited or perfectly appropriate. It emphasizes the high degree of suitability. The other options don't work - extensively means thoroughly, essentially means fundamentally, exactly means precisely, and especially means particularly.

Expertise refers to expert skill or knowledge in a particular field, which perfectly fits the context of impressive skiing performance. People are amazed when someone shows exceptional skill on ski slopes. The other options don't work - disregard means lack of attention, drift means to move slowly, due is an adjective meaning owed, and example doesn't fit grammatically.

Set an excellent example is a standard phrase meaning to demonstrate behavior worthy of imitation. When someone sets a good example, they show others how to behave or perform. The other options don't fit - disregard means to ignore, drift means to move aimlessly, expertise refers to skill (not set in this context), and due is an adjective.

Commit themselves means to pledge, dedicate, or bind themselves to a position or course of action. When criticized for being vague, the criticism is that they won't take a clear stand or position. The other options don't work - collapse means to fall down, collide means to crash into, compel means to force, and conclude means to finish or deduce.

Compress means to condense or squeeze into a smaller space, which perfectly fits the context of shortening an argument into a few sentences. It's about making something more concise. The other options don't make sense - collide means to crash, commit means to dedicate, compel means to force, and cover means to place something over.

In particle physics, collide means to crash into each other with force, which is the standard description of what happens when accelerated particles meet. Particle accelerators are designed to make particles collide at high speeds. The other options don't fit - compress means to squeeze, commit means to pledge, compel means to force, and conclude means to finish.

Essentially means fundamentally or in its basic nature, which fits perfectly when describing the core character of a movement. Saying something is 'essentially X' means that while it may have other aspects, its fundamental nature is X. The other options don't work as well here - extensively means thoroughly, easily means without difficulty, exactly means precisely, and especially means particularly.

Collapse means to fall down, give way, or break down, often from exhaustion or extreme stress. When someone looks ready to collapse, they appear about to fall or faint from physical or emotional strain. The other options don't fit - collide means to crash into something, commit means to dedicate or pledge, compel means to force, and conclude means to finish.

Compel means to force or make someone do something, often through authority or pressure. The sentence acknowledges they lack the power to force action, while still expressing their opinion that the action should be taken. The other options don't make sense - compress means to squeeze, collide means to crash, commit means to pledge, and conclude means to finish or deduce.

Call for help is the standard English phrase meaning to request assistance. The preposition for is the correct choice here as it indicates the purpose or target of the calling. The other prepositions don't work in this context - call in means to summon or retract, call upon means to visit or invoke, call off means to cancel, and call on means to visit or ask.
