Step 1: Identify the relationship in the first pair.
"Eject" means to throw out or expel, while "Insert" means to put in.
These two are antonyms (opposites).
Step 2: Apply the same relationship to the second pair.
We need a word that is the opposite of "Advance."
- Advance = move forward, proceed.
- The opposite (antonym) $\Rightarrow$ Retreat = move back, withdraw.
Step 3: Eliminate the options.
(A) Advent = arrival/beginning (not opposite of advance).
(B) Progress = move forward (synonym of advance).
(C) Retreat = move back/withdraw $\Rightarrow$ correct antonym.
(D) Loan = lending of money (irrelevant meaning).
\[
\boxed{\text{Retreat}}
\]

Select the correct option to complete the analogy.
Consider a reinforced concrete beam section of 350 mm width and 600 mm depth. The beam is reinforced with the tension steel of 800 mm\(^2\) area at an effective cover of 40 mm. Consider M20 concrete and Fe415 steel. Let the stress block considered for concrete in IS 456:2000 be replaced by an equivalent rectangular stress block, with no change in (a) the area of the stress block, (b) the design strength of concrete (at the strain of 0.0035), and (c) the location of neutral axis at flexural collapse.
The ultimate moment of resistance of the beam (in kN.m) is ___________ (round off to the nearest integer).
Two soils of permeabilities \( k_1 \) and \( k_2 \) are placed in a horizontal flow apparatus, as shown in the figure. For Soil 1, \( L_1 = 50 \, {cm} \), and \( k_1 = 0.055 \, {cm/s} \); for Soil 2, \( L_2 = 30 \, {cm} \), and \( k_2 = 0.035 \, {cm/s} \). The cross-sectional area of the horizontal pipe is 100 cm², and the head difference (\( \Delta h \)) is 150 cm. The discharge (in cm³/s) through the soils is ........ (rounded off to 2 decimal places).

The most suitable test for measuring the permeability of clayey soils in the laboratory is ___________.
Consider the beam ACDEB given in the figure. Which of the following statements is/are correct:
