In this context, "food" is used as an uncountable noun, so it does not need the article "the" before it. Thus, the correct sentence should not have the article "the" before "food" to make it
Question : If $\cos ^4 \alpha-\sin ^4 \alpha=\frac{5}{6}$, then the value of $2 \cos ^2 \alpha-1$ is:
Option 1: $\frac{11}{6}$
Option 2: $\frac{5}{6}$
Option 3: $\frac{6}{11}$
Option 4: $\frac{6}{5}$
Correct Answer: $\frac{5}{6}$
Solution : Given: $\cos ^4 \alpha-\sin ^4 \alpha=\frac{5}{6}$ ⇒ $(\cos ^2 \alpha)^2-(\sin ^2 \alpha)^2=\frac{5}{6}$ ⇒ $(\cos ^2 \alpha-\sin ^2 \alpha)(\cos ^2 \alpha+\sin ^2 \alpha)=\frac{5}{6}$ ⇒ $(\cos ^2 \alpha-\sin ^2 \alpha)=\frac{5}{6}$ [As $\cos ^2 \alpha+\sin ^2 \alpha=1$] ⇒ $\cos^2\alpha - 1+\cos^2\alpha=\frac{5}{6}$ [As $\sin^2\alpha=1-\cos^2\alpha$] $\therefore2\cos ^2 \alpha-1=\frac{5}{6}$ Hence, the

Hence, the first option is correct.
Question : Directions: Select the correct mirror image of the given figure when the mirror is placed at line MN as shown.
Solution : As per the mirror image properties, closer things appear close to the mirror in the reflection. Here, according to the information provided, the mirror is placed on the right side of the figure (on Line MN). So, the left side of the reflected image will appear
Question : If $(\frac{x}{y})^{5a-3}=(\frac{y}{x})^{17-3a}$, then what is the value of $a$?
Option 1: –7
Option 2: –5
Option 3: 0
Option 4: 3
Correct Answer: –7
Solution : Given: $(\frac{x}{y})^{5a-3}=(\frac{y}{x})^{17-3a}$ Making the same base for comparison, ⇒ $(\frac{x}{y})^{5a–3}=(\frac{x}{y})^{-(17-3a)}$ ⇒ $5a-3=-(17-3a)$ ⇒ $2a=-14$ $\therefore a=-7$ Hence, the correct answer is –7.
Question : Detritivores in the soil break down detritus into smaller particles. This process is called ______.
Option 1: catabolism
Option 2: mineralisation
Option 3: fragmentation
