Now, the educational courses in many institutions are sold and even __________ for _________ prices.
Look for words that match the tone: "sold" → "auctioned" and "high" → "fabulous prices."
Step 1: The sentence indicates commercialization of education — courses are being "sold" and even further exploited.
Step 2: Among the options:
- (a) auctioned, fabulous → makes sense, as "auctioned" matches with "sold" and "fabulous prices" indicates very high costs.
- (b) glamourised, soaring → grammatically odd and doesn't fit with "sold."
- (c) bought, competitive → "competitive prices" usually means cheaper, which doesn't convey commercialization.
- (d) advertised, cover → incorrect usage of "cover prices."
Step 3: Hence, the best fit is option (a). \[ \boxed{\text{auctioned, fabulous}} \]
A quick way to solve this is to test the escalation logic of the sentence as a whole, rather than judging each word in isolation. The sentence already states courses are "sold" — the missing verb must show something happening beyond mere selling, and the missing adjective must describe an extreme, undesirable price.
Only option A keeps the escalation from "sold" intact and pairs it with a price description that fits the sentence's critical tone.
Hence, the correct answer is auctioned, fabulous.
