TOEIC Test 28 - Fill In The Blanks

The phrase “expressions of interest” is a common formal collocation used in professional communication. It refers to people showing their willingness to participate. Other options like “emails” or “ideas” do not fit naturally in this context. “Indications” is close but less standard in this phrase. Therefore, “expressions” is correct because it forms the proper and widely accepted expression used in formal invitations.

“Highly regarded” means respected and well-known for expertise, which fits the context of educators from prestigious universities. Other options like “excellent” or “professional” are too general, while “famous” focuses on popularity rather than respect. Therefore, “highly regarded” is correct because it accurately describes the credibility and reputation of the speakers in an academic setting.

The phrase “ranging from…to…” is a fixed expression used to show a variety of topics. Other options like “between” or “starting” do not fit grammatically with this structure. Therefore, “ranging” is correct because it clearly indicates that the seminar sessions will cover a wide range of subjects, making the sentence complete and natural in formal English.

The word “form” is correct because it refers to an official document that participants must complete to register. Other options like “interview” or “ideas” do not fit the context of registration. Therefore, “form” is correct as it logically describes the required document used for collecting participant information in formal processes like seminar registration.

The phrase “first come, first served” is a fixed expression meaning that priority is given based on order of arrival. Other options do not form a meaningful or grammatically correct phrase. Therefore, “served” is correct because it completes the well-known expression used to describe fair allocation based on timing.
